Thanks @Alex Johnson - We do this type of development work for every Brock's performance exhaust we sell, and have for many years. Our biggest issue is that we don't have access to bikes early (like the bike guys) so we have to start product development after the bikes hit dealer floors - it takes us a little longer, but the wait is worth it.
Man I tell ya...you just gotta love the fact on how this man takes the time to explain and educate his consumers/fans about his products and how they work. Been looking at that AH2 lately tho...👀
Outstanding Brock. All that hard work, and video editing, people have no idea. The sound of the Alien Head 2 exhaust was beastly, an experience in of itself, wow! 190-195 hp range with huge torque after tuning with the Alien Head 2 on pump gas. So we probably have 190+ hp on pump gas for Predator Exhaust Titanium (road racing), 15 lbs less weight, and great sound. Suzuki nailed it, from stock to Brock, I love it. This bike is going to be amazing on the track, untouchable with the right rider, both road racing and drag! After watching this, I think I'm going to have to set my traction control 1 setting safer when all is bolted and dusted :-) Dang what a machine!! Nice Brock, very nice. It just keeps gettin' better.
Hello Brock, love your videos bro. My question to you is; I just bought a new 2017 250cc Formula sportbike; i love the design but, i,am a little worried that it maybe a little under power because i had a 600cc sportbike before and i,am afraid that i might have bought a bike thats going to be under power than what i,am used to. Can i do any power upgrades to enhanced the speed of my 250cc sportbike to my liking.
You’ve made it simple for a lot of guys that don’t know anything about exhaust systems. It also takes a real technician to admit when they are wrong. Brock’s is the best street exhaust system. Best sound ever!!!!!
I needed delete my comment, Due to another failure to get the Motorcycle I was after, Today I went down and Signed the Final Paper Work for a 2017 Suzuki GSX-R1000R ABS Model. Looking so Forward to getting some parts and a Full exhaust from you!!! Just Beautiful they are, Truly!!!!! I really enjoy these Video's. I am sure you'd be a great School Teacher. Just the way you explain things, you have a way of making what you are talking about understandable, For myself, I really appreciate that, really do. It is Obvious you do care about the products you sell. You take good care. Thank you!!! PS---Pick up my Bike in about 34 Hours. :) Deal has been finalized this time. Like a Kid waiting for ol'Santa at Xmas.
@liveatvictoria Glad you like our series. You are correct, I care about our products very much - and have a fantastic staff who care as much as I do. Give us a call to help you take your new bike from Stock to Brock!
I am going to need save a bit, it was with a little help from my Dad---who I care for, only reason I accepted his help, least I can work it off, but when I do save enough, Be sure I will definitely be Going From Stock to Brock. I mentioned your series to the salesman, got a big grin, found out that he races, has an '88 GSX-R750 looks really good in the pictures he showed me, says it is going from what it is now to Brock and more, I knew of the track up island (Vancouver Island) but he goes over to Washington State says there a Track on the Olympic Peninsula he goes regularly, has a great straightaway tells me can get up to full speed--(I always take with a grain of salt, am 50 not,.... :) but does sound good) Thank you for the reply I mean everything I say. Would you recommend the Zero weight Alisyn and Petron for the first change and thereafter??
liveatvictoria the Alisyn and petron combination are great for racing. For street use, the fully synthetic Suzuki oil recommended for the bike is a great choice.
Thank you kind Sir :) . I appreciate that. Can go get my bike, it's about an hours slow walk to Esquimalt from my house, making arrival about Perfect time. Thank you again for the information. I have never had a Brand new Motorcycle. Have a nice Weekend. :)
Seriously AWESOME stuff!! Thank you Brock for yet another lucid, informative and imminently interesting video. This 34 minute segment felt like 5 minutes to me. Very much looking forward to the next episode. Best!
@ Brock Davidson , man you're killing the competition the proof is in the pudding & it's great people like you manufacturing mint American products that out perform Thanks for the great content.
rode a 14r with an alien head on it. no tuning or air filter. just this exhaust. i swear, the sound it makes when you cut the throttle at 10k+ rpm, it feels like a sonic boom! such a quality system.
See description for detailed information and video time tags. Might want to grab some popcorn also, as we cover A BUNCH of #stupidfast exhaust information.
Brock Davidson from the video we seen on 650 ib it looks like the Gsxr1000 rr cant compete with the the bmw 1000 r and the zx10 r and rr model .... so is it all hype ??? Or can it compete against the new 17 model bikes ???
@99gsxrboy - Please don't let 650Ib's slowness let you create a false impression of this bike. I LOVE the guy, but he is too big to be racing 1000's and, especially taking apples vs. oranges races. Our new gixxer is already producing power numbers equal to or better than most modern 1000's, and we still haven't tuned it yet or done any of the other things we do to make bikes 'race ready'. We will have this bike flying a soon as all of the parts and tuning capabilities are available.
Brock Davidson love this series. Can you do a naked bike once you are done with this bike? Nakeds are getting a lot more popular (I have one) and I'm interested in the gsxs 750-1000. I'm curious as to what the bike would be like when it is unrestricted and tuned properly. Keep up the good work brother.
Brought my bike there and Brian made it a beast with all your accessories! Fastest bike in my area! Thanks brocks! U made my bike a beast! Green 2012/zx10r
34hp holy shit. Hahaha thats a huge gain for a customer when comparing to out of the box. (Ecu flash obviously helps a lot) but seriously people were already comparing these and they were fast because of the way they produce their power in a very liner fashion. With a top end now to boot on it, it is going to be an absolute weapon.
Wow, Brock you're a genius! Certainly looking forward to seeing more of this, I'm sure that once you're finished with the GSXR it will be a monster! Fine tuning and I'm sure you'll be over 200 quite easily. Once I've moved to the US you'll be the guy I use.
Brock their was a day long long time ago back in 1980, my beast the H2 750 with Denco Chambers it was so dam loud that you couldn't hear the space shuttle, lol. Them were the days I would go to Lang Hindles garage watching him fabricating Headers for his KZ 900 along with KZ1000. Back in them days if you built it right you got big power out them pipes, but major pain in the ass jet remember Lang had large board from everything from pilot jet , air, jet,, but most important the needle jet shims just get it spot on. For top end performance I was the Ginny pig that would go on the highway have screaming every year till 4th cut the engine pull over side remove all 4 plugs just to see the colours. We've come a long way not only the nightmares of having them run well, but today pipes are built so well so much R&D goes into them. Mostly great weight savings nice sound. Yet to see a pipe give out over 20 HP like golden era of superbike. Brock I been trying to work on bikes from the triples no Suzuki's, lol, when things really heated up 80s big bore love that GS 1150, to real superbike days 1985 that the year we owe all this to that era. Great job Mr. Davidson love learning from you real have great gift even the squids can lean a thing or two from you. Cheers from 🇨🇦🇨🇦
Absolutely brilliant series and love all the technical jargon. Keep at Brock, munching my nails for the next episode already. :) Keep it on the black stuff.
"Less negative pressure", absolutely makes a huge difference, and how do I know this? I run a custom vacuum still, sometimes 1000 millibars below atmospheric pressure, and I can tell you even a 10 millibar variance can make a huge difference in the performance of the still, and we are talking about less negative pressure not positive pressure. Now while a still and gasoline combustion engine have a lot differences, the range of vacuum (pressure) in both is paramount to optimum performance.
Just stuck a full arrows titanium system on mine, bmc race filter, ecu flash and fueling work, got from 176 standard to just over 185 peak and 80 to 83 foot pounds of torque, but picked up nearly a 20bhp gain in the midrange, from 6k through to 12ķ and you can really notice it, the throttle response is like butter now, the engine had only just covered 1000 miles, so its going back in at 4k for another dyno session as it should of loosened up by then
I can't tell you enough how much I'm enjoying this "series". It's like waiting for a new episode of Game of Thrones, or The walking Dead. That exhaust sounds awesome!! If I were getting a 2017 GXS-R 1000R I'd seriously consider the full titanium exhaust. (plus full ecu flash etc etc. Hope you ship to australia). Atm I'm still in the '17 CBR1000 SP camp, though it is just about 50/50. lol. There will definitely be a new bike for me next year, so still have some time to make up my mind. Question, doesn't ECU tuning eliminate the need for a Power Commander?
I love these videos. Very smart guy. Knows his shit. I've was a motorcycle tech for a while and I roadcourse race. I've never been this in depth with exhaust and ecu tuning. I love it. Keep the videos comming
Great videos Brock. Just quality stuff. Learning a lot just from watching. I can tell you're a man who knows his craft very well and I can tell you love what you do. Cheers from toronto Canada buddy
Man I really appreciate watching that. I have dabbled with an exhaust on my friends bike and I can tell ya that .063 larger on the choke and id woke it up crazy.
This is genius. Took me about 5 videos before I realized these are all sales videos, *not* tutorials. The shop, the dyno, and every product used & featured, from fluids to pipes, are all available for sale, by Brock
Thanks! And yes, while we educate the consumer of the best products to use - since we use what we sell-we also make the products available to them...if we don't, they get angry.
These videos are really good, everything is explained very well. Your exhaust have been known for their performance and quality, I just can't get over the look of the cans, everything else looks awesome.
Brock Davidson Hey, personally, I don't like the megaphone look, or the tapered look. I think Akrapovic exhaust probably looks the best. Cans have a good shape and sound amazing, but could be louder. I also like how they etched the name on the can on the R1. Nice clean look. I have an 07 10R, and would have bought the Racefit Growler if I didn't have to shave the swing arm, but I do like the undertail exhaust. Just my opinion, not bashing. Thanks for the in-depth videos.
stupid fast and the most beautiful sound. I saw a zx10r here in Turkey equipped with Brock exhaust. It was amazing. I cant explain my feelings by words :) amazing man. I am looking forward for s1000rr 2017 work from you. take care. and by the way I know you via @650ib ;)
Hey Brock, great video and info as everyone else has already stated. I thought you forgot about this series, I have been waiting and waiting even though I'm subscribed, I still was just your website and if to make sure I didn't miss a video. Come out with the next one quickly please lol! Since you say the drag strip is a great tool, will you test the alien head exhaust with flashed ecu and tuned against the predator exhaust flashed and tuned. Since they both make similar numbers without tuning, I'm curious to see how they perform in real world application. I don't know about any other but when I watch your videos, I take notes. There aren't too many motorcycle info vids that gives solid info like that out there that make me feel like I have to write down. Keep up the great work. I like the headers on the alien head but not the muffler so much. Do you have any plans to have different looking mufflers that will fit the different headers like the alien head and predator design? I personally think this would be a lucrative financial benefit for your company.
Thanks. FYI: a 20 minute vid can take 50+ man hours to produce - we would love to make them all day, but we wouldn't have time to actually work. Keep watching our GSX-R1000 product page for new items: www.brocksperformance.com/brocknm/templates/bpp1.aspx?articleid=831&zoneid=22
I can't say anything more than that. This is the real reason why mix-n-match doesn't work that great, but because of real engineering and design, now we can have a solution that can work. I mean, before all these ECU stuff we'd have to struggle so much only to see we're not getting any midrange power. Nowadays, with all the electronics and the restrictions on these bikes, the simpler you think the easier it is. Hahaha.
It amazing me how much of this stuff matters. I dont know anything about exhausts and was always under the impression, exhaust shit as fast as possible = best. Randomly stumbled across this video and I am glad I did, very interesting Brock. New GSX-R is a real beauty too. Pure out of curiosity, what would be the benefits or downsides of ending the exhaust before it even goes under the bike and exhausting it to the ground or sides. Aside from weight saving ,would it reduce performance anywhere? Because as you explain with the drag pipe, moving air, shortening the pipes would mean it moves air out faster wouldn't it?
Thanks! And great question. Extremely short headpipes can seriously hamper low-end performance in naturally aspirated situations. You will notice that most turbo charged and almost all supercharger race bikes have very short exhausts, as their power adders compensate for any reduction in low-end. Our Alein Head is as compact as we know how to make a short pipe - the muffler itself is a short/tapered megaphone, which helps eliminate the need for a longer elbow pipe to keep peak power high and not hamper mid/low end power due to minimized overall lenght.
As a general rule, full systems require more fuel for a proper tune. This extra fuel in the cat can eventually clog it up, as well as reducing its ability to control emissions. This FAQ might help you a bit also (it applies to most modern bikes, as well as your 675R: blog.brocksperformance.com/faq/do-i-need-a-pcv-when-installing-a-brocks-performance-exhaust-system/
isn't the predator supposed to be bit better at mid range and the alien head a little more at top end (wider and shorter)? number are exactly the same with a little gap at 8k on the predator
Thank you for the time you are putting in your videos. Well, I think I have to disagree with you on some points. When you installed Brock's exhaust, the engine benefited from the the overly rich mixture the factory ECU is set at. The N/A factory engine benefit from slightly larger pipes by the fact that larger pipes draw more of the exhaust gas out of the cylinder mainly due to the change in the absolute pressure between the cylinder and the exhaust pipes. When the cylinder is emptier, during the next intake cycle, the piston creates more vacuum which leads to withdrawing more air into the cylinder. And since factory A/F map was already set at a very rich condition, the additional air will make use of it. So, to be fair, Brock's exhaust and whatever aftermarket performance exhaust for the sake of argument, took advantage of the unbalanced A/F ratio the factory set their ECU's at. Vehicle manufacturer, across the industry, tend to enriching their fuel mixture to meet the emission since richer fuel mixture has lower gas degree, it will lower the production of Ozone and Nitric Oxide. At the same time, richer mixture produces greater amount of carbon monoxide and carbon dioxide, but these residuals got taken care of by the catalytic converter. Just to pin point what I at talking about, go back to time 30:15 in the video and you will see the run with the factory exhaust had A/F is 8.03 and when you installed the performance exhaust, the A/F went up to 11.73. I think we both agree that 8.03 ratio is super rich and 11.73 is close to ideal ratio. I am not saying the performance exhaust did not aid in power, but I can't claim all the additional 13.09 hp & 8.56 torque was due to the performance exhaust. What I would like to see is EITHER to put the factory exhaust on the bike and re-tuning the factory ECU to exactly match the A/F that is produced after the performance exhaust was installed, I know that would be tremendous work. OR, putting factory exhaust back and tune the ECU to the optimal performance point then put the performance exhaust and re-tune the ECU to its new configuration THEN comparing the two figures together. Because of what I am seeing here, I see that the factory map is not optimized for performance and its not at its best set up for the factory exhaust, I mean come on A/F of 8.03 is way off of the performance band. To me, it looks the bike needs tuning more than any other thing. Sorry for the long comment, have a good day.
Thank you for your input. We do not agree that 11.73 is close to the ideal ratio. What you would like to see sounds interesting, but not anything we would be interested in testing as an aftermarket performance company. If you test it, let us know your results.
Great stuff brock! Another point to make about the crossovers on the exhaust are they even out the pulse width of the exhaust to decrease back pressure of the exhausting piston and increase back pressure on the piston preparing to fire creating more torque supposedly. Big fan of your work! Im sure you will pick up 10hp easy once you tune the commander for the exhaust and put an intake on it. We will probably be looking at a 205hp bike pretty soon. How much you want for it when you're done playing with it? LOL
I was afraid we already crossed the 'boundary of understanding' for some viewers, lol. Yes, this bike will be for sale at the end of the project. I have no idea on the cost as we haven't decided what products will be added, etc.
the more i watch your vids, the more I realize i made some bad decisions. I make pore power than most guys with the same bikes here, but i feel like i should have gone with brocks. Seems like yall really go the extra step.
@ phatrides222000 We are always available if you decide to step up your program. Our customer service team will even discount our pipe if you tell them you removed another aftermarket system to go with ours. Call 937-912-0054 or email sales@brocksperformance.com for details.
Brock, I wanted to say that I really appreciate these videos. I am an engineer, and I love to see how you go about designing your exhausts. And the gains that you achieve are frankly incredible. I am assuming that you are talking about Akra and Yoshi when you say that the company with thousands of exhausts sitting in a warehouse isn't going to sell "you" an exhaust that makes your bike run poorly? I love the work you do, but sadly I just don't agree with the styling of your mufflers. I never have been a fan of the megaphone look. Based on these videos, I am assuming that the design comes from some engineering reason? Anyways, despite me not liking the styling, keep up the awesome work, and I love these videos!
ilarson007 thank you for your input. Do you have a problem with the look of our Predator mufflers? www.brocksperformance.com/brocknm/templates/bpp1.aspx?articleid=831&zoneid=22 Also, you are 100% correct. The Alien Head muffler begins it's life as a round megaphone - we 'squish' it into the Alien Head shape. You are 100% correct: it is a short megapone on the end of a short system... to boost performance.
Brock Davidson the Predator mufflers definitely look better to me than the Alienhead ones. I'm glad that there is an engineering reason behind the shape lol. Unfortunately though, as much as I love GSX-Rs and the new GSX-R, money dictates I'm not going to be able to pick one up. I'm shooting for a 2017 FZ-09, which you only offer the Alienhead for. I'm sure the FZ is a much smaller market segment than the GSX-R is for you, and I understand needing to focus resources where the ROI is there. As much as it sucks, you can't develop all exhausts for all bikes.
Hello from the US @patrick - we don't produce components for the GSX-S1000 at this time, but we have received enough requests to start looking into them.
What I'm getting from these videos is that the majority of the horsepower gains come from deristricting the throttle alone. the mapping gives a little bit extra but not by as much. Is that correct?
From a purely power standpoint, that's becoming the case more and more. The problem is that while this is going on, driveability continues to suffer even more... Which makes proper mapping critical not only when it comes to power and rideability, but also acceleration.
@BIKE GEAR. Both exhausts shown are available in Black. Predator has an exclusive black stainless muffler available: www.brocksperformance.com/Predator-Ti-Full-System-W-SS-ElectroBlack-Muffler-+I571179+C134.aspx and the Alien Head is available in black ceramic coating: www.brocksperformance.com/Alien-Head-2-Full-System-Black+I398685+C241.aspx
Hi Broc, is there a difference between the sensors on european bikes? I heard most bikes don’t have O2 sensors in the USA. I hope you can help me with the following question: I have a 09 zx6r with a slip on pipe + link pipe. The headers are stock and the cat is still in. I want to install a bmc race filter. Now do i need to keep everything as it is or is a full system required? If so, would my bike run lean and bad if i don’t flash my ecu after full system install? Would it run lean from installing the bmc race filter alone? Thanks in advance! Best regards Donny from Holland
Hey Mr. Brock I need a full exhaust for my bmw s1000rr 2018. I would prefer titanium over stainless if you have it. If you can give me some info on where to purchase your products I will definitely buy this system or one suitable for my make and model bike. Thanks man
Thanks for taking the time to get so in depth. Not a lot of people out there that will do this.
Thanks for your appreciation @BOOSTEDH2
I am buying a Brocks full system and tune for sure over their competitors after seeing these videos.

Don't need popcorn,you feed brains well enough.
Thank you for your work,and the instructive entertainment wich followed it.
Your honesty sells it all. Fantastic! Made a customer out of me.
me too. this guy is a genius.
I've literally watch this series in full over and over and over again. So many details to learn from these videos.
Glad you like!

As am avid road racer and GSXR 1K owner, this has got to be the most informative exhaust flow video on YT. Preciate it Brock.
I have alot of respect for Brock's after watching this (and a few other) videos. Shows some good American ingenuity

Never bored while watching your series 👍

im 3 years late to this video, i dont even own a motorcycle but damn i really enjoy this series.
Brock their was a day long long time ago back in 1980, my beast the H2 750 with Denco Chambers it was so dam loud that you couldn't hear the space shuttle, lol. Them were the days I would go to Lang Hindles garage watching him fabricating Headers for his KZ 900 along with KZ1000.

Brock's Performance exhaust is the best looking sounding available IMO.
Also love how all comments are positive! Can't wait for next video
Wow!!! I ride an Aprilia but somehow the language about this Suzuki makes more sense. Maybe I need to buy one! Great video thanks!!
Absolutely brilliant series and love all the technical jargon. Keep at Brock, munching my nails for the next episode already. :) Keep it on the black stuff.
That's insane! Great work, guys. Can't wait to see what you can get with more tuning.
"Less negative pressure", absolutely makes a huge difference, and how do I know this? I run a custom vacuum still, sometimes 1000 millibars below atmospheric pressure, and I can tell you even a 10 millibar variance can make a huge difference in the performance of the still, and we are talking about less negative pressure not positive pressure. Now while a still and gasoline combustion engine have a lot differences, the range of vacuum (pressure) in both is paramount to optimum performance.
It's still negative, but at least it's less. That alone is a good thing!
Just stuck a full arrows titanium system on mine, bmc race filter, ecu flash and fueling work, got from 176 standard to just over 185 peak and 80 to 83 foot pounds of torque, but picked up nearly a 20bhp gain in the midrange, from 6k through to 12ķ and you can really notice it, the throttle response is like butter now, the engine had only just covered 1000 miles, so its going back in at 4k for another dyno session as it should of loosened up by then
BROCKS IS DEF ONE OF THE BEST EXHAUSTS ON THE MARKET PERIOD ! GLAD I HAVE THEM ON MY ZX14-R
I can't tell you enough how much I'm enjoying this "series".
It's like waiting for a new episode of Game of Thrones, or The walking Dead.
That exhaust sounds awesome!! If I were getting a 2017 GXS-R 1000R I'd seriously consider the full titanium exhaust. (plus full ecu flash etc etc. Hope you ship to australia).
Atm I'm still in the '17 CBR1000 SP camp, though it is just about 50/50. lol. There will definitely be a new bike for me next year, so still have some time to make up my mind.
Question, doesn't ECU tuning eliminate the need for a Power Commander?
Thanks! Yes- a properly tuned fuel flash in the ECU can eliminate the need for a power commander. We will discuss this in detail in a later episode.
I love these videos. Very smart guy. Knows his shit. I've was a motorcycle tech for a while and I roadcourse race. I've never been this in depth with exhaust and ecu tuning. I love it. Keep the videos comming
Great videos Brock. Just quality stuff. Learning a lot just from watching. I can tell you're a man who knows his craft very well and I can tell you love what you do. Cheers from toronto Canada buddy
Man I really appreciate watching that. I have dabbled with an exhaust on my friends bike and I can tell ya that .063 larger on the choke and id woke it up crazy.
really just started getting into the tuning and drag racing channels. this channel is a gem, sir. keep it up
Glad you enjoy it! Tell your friends about us 😀
definitly worth the wait amazing series
And that's why Brook is the good standard. I've been saving my cash to buy a full system and ecu flash. Hopefully the end of summer
This is genius. Took me about 5 videos before I realized these are all sales videos, *not* tutorials.
The shop, the dyno, and every product used & featured, from fluids to pipes, are all available for sale, by Brock
Thanks! And yes, while we educate the consumer of the best products to use - since we use what we sell-we also make the products available to them...if we don't, they get angry.
These videos are really good, everything is explained very well. Your exhaust have been known for their performance and quality, I just can't get over the look of the cans, everything else looks awesome.
Thanks for your input. What would you rather see?
Brock Davidson Hey, personally, I don't like the megaphone look, or the tapered look. I think Akrapovic exhaust probably looks the best. Cans have a good shape and sound amazing, but could be louder. I also like how they etched the name on the can on the R1. Nice clean look. I have an 07 10R, and would have bought the Racefit Growler if I didn't have to shave the swing arm, but I do like the undertail exhaust. Just my opinion, not bashing. Thanks for the in-depth videos.
Absolutely brilliant thanks for your time and hard work mate
Brock, you are a legend
Looking to get a GSXR 1000R and I'll be adding Brock's goodies good video nice in-depth explanation
Really appreciate your passion & honesty. Thank you.
I wish I lived near this shop! Stuck in NY with no real options for professionalism like this!
Great video, really interesting stuff! Now i'm more interested in your products! Two thumbs up!
Btw Brock Davidson before i went turbo i purchase a brocks alien head 1 for my 99/2000 hayabusa in 2013 it was the best exhaust i ever had ....
your right on the money brock great job.
stupid fast and the most beautiful sound. I saw a zx10r here in Turkey equipped with Brock exhaust. It was amazing. I cant explain my feelings by words :) amazing man. I am looking forward for s1000rr 2017 work from you. take care. and by the way I know you via @650ib ;)
Yes!!!!!! I've been waiting.
Another high quality video! Keep up the good work. I look forward to the next one.
Thanks Brock, I've been waiting for this to come out.
fxcking love the look of the gsxr especially with that exhaust
Brock you should do an exhaust comparison between the Ct Meg , short meg, alien head, & predator system on the new GSXRs
You da man Brock!
Hey Brock, great video and info as everyone else has already stated. I thought you forgot about this series, I have been waiting and waiting even though I'm subscribed, I still was just your website and if to make sure I didn't miss a video. Come out with the next one quickly please lol! Since you say the drag strip is a great tool, will you test the alien head exhaust with flashed ecu and tuned against the predator exhaust flashed and tuned. Since they both make similar numbers without tuning, I'm curious to see how they perform in real world application. I don't know about any other but when I watch your videos, I take notes. There aren't too many motorcycle info vids that gives solid info like that out there that make me feel like I have to write down. Keep up the great work. I like the headers on the alien head but not the muffler so much. Do you have any plans to have different looking mufflers that will fit the different headers like the alien head and predator design? I personally think this would be a lucrative financial benefit for your company.
Thanks. FYI: a 20 minute vid can take 50+ man hours to produce - we would love to make them all day, but we wouldn't have time to actually work. Keep watching our GSX-R1000 product page for new items: www.brocksperformance.com/brocknm/templates/bpp1.aspx?articleid=831&zoneid=22
I can't say anything more than that. This is the real reason why mix-n-match doesn't work that great, but because of real engineering and design, now we can have a solution that can work. I mean, before all these ECU stuff we'd have to struggle so much only to see we're not getting any midrange power. Nowadays, with all the electronics and the restrictions on these bikes, the simpler you think the easier it is. Hahaha.
Another brilliant video Brock. Jim, Australian fan
That flash would work on stock exhaust to. Show derestricted ECU with stock ECU.
It amazing me how much of this stuff matters. I dont know anything about exhausts and was always under the impression, exhaust shit as fast as possible = best. Randomly stumbled across this video and I am glad I did, very interesting Brock. New GSX-R is a real beauty too.
Pure out of curiosity, what would be the benefits or downsides of ending the exhaust before it even goes under the bike and exhausting it to the ground or sides. Aside from weight saving ,would it reduce performance anywhere? Because as you explain with the drag pipe, moving air, shortening the pipes would mean it moves air out faster wouldn't it?
Thanks! And great question. Extremely short headpipes can seriously hamper low-end performance in naturally aspirated situations. You will notice that most turbo charged and almost all supercharger race bikes have very short exhausts, as their power adders compensate for any reduction in low-end. Our Alein Head is as compact as we know how to make a short pipe - the muffler itself is a short/tapered megaphone, which helps eliminate the need for a longer elbow pipe to keep peak power high and not hamper mid/low end power due to minimized overall lenght.
Excellent vid Brock
sounds awesome brock :)
Hi Brock what would happen if I install a full system map with a slip on. The bike is a street triple 675R with a small catalyst
As a general rule, full systems require more fuel for a proper tune. This extra fuel in the cat can eventually clog it up, as well as reducing its ability to control emissions. This FAQ might help you a bit also (it applies to most modern bikes, as well as your 675R: blog.brocksperformance.com/faq/do-i-need-a-pcv-when-installing-a-brocks-performance-exhaust-system/
Keep them coming, fascinating stuff! Ty!
First of all : awesome video ! second : could you compare the predator to the alienhead ?
PLEASE !!!!
Did you see this? facebook.com/BrocksPerformance/videos/10154655332516472/
I didn't see that before, thanks
isn't the predator supposed to be bit better at mid range and the alien head a little more at top end (wider and shorter)?
number are exactly the same with a little gap at 8k on the predator
That's on two different bikes. Lukes R model with more miles/different fuel etc... it's only for general comparison.
That engine has loads left, Michael Dunlop was 0.007mph off setting a new average lap record (133mph) at this years IoM TT.
Great video and very informative!
Thank you for the time you are putting in your videos. Well, I think I have to disagree with you on some points. When you installed Brock's exhaust, the engine benefited from the the overly rich mixture the factory ECU is set at. The N/A factory engine benefit from slightly larger pipes by the fact that larger pipes draw more of the exhaust gas out of the cylinder mainly due to the change in the absolute pressure between the cylinder and the exhaust pipes. When the cylinder is emptier, during the next intake cycle, the piston creates more vacuum which leads to withdrawing more air into the cylinder. And since factory A/F map was already set at a very rich condition, the additional air will make use of it. So, to be fair, Brock's exhaust and whatever aftermarket performance exhaust for the sake of argument, took advantage of the unbalanced A/F ratio the factory set their ECU's at. Vehicle manufacturer, across the industry, tend to enriching their fuel mixture to meet the emission since richer fuel mixture has lower gas degree, it will lower the production of Ozone and Nitric Oxide. At the same time, richer mixture produces greater amount of carbon monoxide and carbon dioxide, but these residuals got taken care of by the catalytic converter. Just to pin point what I at talking about, go back to time 30:15 in the video and you will see the run with the factory exhaust had A/F is 8.03 and when you installed the performance exhaust, the A/F went up to 11.73. I think we both agree that 8.03 ratio is super rich and 11.73 is close to ideal ratio. I am not saying the performance exhaust did not aid in power, but I can't claim all the additional 13.09 hp & 8.56 torque was due to the performance exhaust. What I would like to see is EITHER to put the factory exhaust on the bike and re-tuning the factory ECU to exactly match the A/F that is produced after the performance exhaust was installed, I know that would be tremendous work. OR, putting factory exhaust back and tune the ECU to the optimal performance point then put the performance exhaust and re-tune the ECU to its new configuration THEN comparing the two figures together. Because of what I am seeing here, I see that the factory map is not optimized for performance and its not at its best set up for the factory exhaust, I mean come on A/F of 8.03 is way off of the performance band. To me, it looks the bike needs tuning more than any other thing. Sorry for the long comment, have a good day.
Thank you for your input. We do not agree that 11.73 is close to the ideal ratio. What you would like to see sounds interesting, but not anything we would be interested in testing as an aftermarket performance company. If you test it, let us know your results.
Was sold, ready to buy a full exhaust for my 06 R1. Went to your website and all. Kinda bummed you don't make r1 full exhaust setups. Oh well.
Sorry Disarray 09 - we discontinued those a while back.
Allways good 2 to watch, you meke good videos
Love watching your videos. Very informative and helpful
Great stuff brock! Another point to make about the crossovers on the exhaust are they even out the pulse width of the exhaust to decrease back pressure of the exhausting piston and increase back pressure on the piston preparing to fire creating more torque supposedly.
Big fan of your work! Im sure you will pick up 10hp easy once you tune the commander for the exhaust and put an intake on it.
We will probably be looking at a 205hp bike pretty soon. How much you want for it when you're done playing with it? LOL
I was afraid we already crossed the 'boundary of understanding' for some viewers, lol. Yes, this bike will be for sale at the end of the project. I have no idea on the cost as we haven't decided what products will be added, etc.
Brock is the hands down
Wish you would make the predator exhaust system for the K7 1000...Brock.
OMG... That direct jab towards Akrapovic :'D
You sir are a true gentleman omg, I am still laughing. I almost spit my coffee out.
the more i watch your vids, the more I realize i made some bad decisions. I make pore power than most guys with the same bikes here, but i feel like i should have gone with brocks. Seems like yall really go the extra step.
@ phatrides222000 We are always available if you decide to step up your program. Our customer service team will even discount our pipe if you tell them you removed another aftermarket system to go with ours. Call 937-912-0054 or email sales@brocksperformance.com for details.
Brock, I wanted to say that I really appreciate these videos. I am an engineer, and I love to see how you go about designing your exhausts. And the gains that you achieve are frankly incredible. I am assuming that you are talking about Akra and Yoshi when you say that the company with thousands of exhausts sitting in a warehouse isn't going to sell "you" an exhaust that makes your bike run poorly?
I love the work you do, but sadly I just don't agree with the styling of your mufflers. I never have been a fan of the megaphone look. Based on these videos, I am assuming that the design comes from some engineering reason?
Anyways, despite me not liking the styling, keep up the awesome work, and I love these videos!
ilarson007 thank you for your input. Do you have a problem with the look of our Predator mufflers? www.brocksperformance.com/brocknm/templates/bpp1.aspx?articleid=831&zoneid=22 Also, you are 100% correct. The Alien Head muffler begins it's life as a round megaphone - we 'squish' it into the Alien Head shape. You are 100% correct: it is a short megapone on the end of a short system... to boost performance.
Brock Davidson the Predator mufflers definitely look better to me than the Alienhead ones. I'm glad that there is an engineering reason behind the shape lol.
Unfortunately though, as much as I love GSX-Rs and the new GSX-R, money dictates I'm not going to be able to pick one up. I'm shooting for a 2017 FZ-09, which you only offer the Alienhead for. I'm sure the FZ is a much smaller market segment than the GSX-R is for you, and I understand needing to focus resources where the ROI is there. As much as it sucks, you can't develop all exhausts for all bikes.
NICE, I love yall think!!!!! I wish I could bring my BIKE you guys!!!!
Love your excitement! blog.brocksperformance.com/faq/do-i-need-to-physically-bring-my-bike-to-brocks-performance-in-ohio-for-a-performance-tune/
Very interesting yet again thank you
Brock you're a prodigy
Very well explanation Brock's...... thank you!
Waiting on the next video 👍👍
Hi bro, I got F1 code on my 2017 Gsxr 1000 and they told be its from the exhaust, so you have any idea how to fix it ? Thanks
brocksperformance.com/engine-clutch/electronics-ignition/brock-ecu-flash/suzuki/
Hey brock greetings from Australia
Awesome video brother!
Any exhuast for a GSXS 1000 2015-2017 ?
I’d love to buy one of you cheers
Hello from the US @patrick - we don't produce components for the GSX-S1000 at this time, but we have received enough requests to start looking into them.
@Brock - BTW, the lathe and knee mill are making me drool :-)
What I'm getting from these videos is that the majority of the horsepower gains come from deristricting the throttle alone. the mapping gives a little bit extra but not by as much. Is that correct?
From a purely power standpoint, that's becoming the case more and more. The problem is that while this is going on, driveability continues to suffer even more... Which makes proper mapping critical not only when it comes to power and rideability, but also acceleration.
this dude knows what his talking about!. just look at how he transformed 650ib ninja h2!
Hahaha I just sent a message to your website asking when the next episode would be then Turned on to CZcams and it's up lmfao
Yeah, this one took a while
It's all good brother Im loving this series can't wait for the next video. Makes me want to go buy one haha
Thank you brock for these videos.. I love the details, actually makes me want a gsxr tuned by brock lol I need to move to USA...
Get in Lane 54 we ship to international customers :)
Brock you should make that same exhaust in all black.
@BIKE GEAR. Both exhausts shown are available in Black. Predator has an exclusive black stainless muffler available: www.brocksperformance.com/Predator-Ti-Full-System-W-SS-ElectroBlack-Muffler-+I571179+C134.aspx and the Alien Head is available in black ceramic coating: www.brocksperformance.com/Alien-Head-2-Full-System-Black+I398685+C241.aspx
I WANT MORE!
Fantastic,, video.
I will b in the market for a new exhaust system when I buy my new Gsxr 1000
Will will have a full line, soon.
I knew it takes a good while. That's my own selfishness I guess. How about the other questions I had. Thanks for the reply.
lol, you aren't alone.
Gretting from Greece man, awesome videos !
Yes! finally Part 3
Hi Broc, is there a difference between the sensors on european bikes? I heard most bikes don’t have O2 sensors in the USA. I hope you can help me with the following question: I have a 09 zx6r with a slip on pipe + link pipe. The headers are stock and the cat is still in. I want to install a bmc race filter. Now do i need to keep everything as it is or is a full system required? If so, would my bike run lean and bad if i don’t flash my ecu after full system install? Would it run lean from installing the bmc race filter alone? Thanks in advance! Best regards Donny from Holland
Hey Mr. Brock I need a full exhaust for my bmw s1000rr 2018. I would prefer titanium over stainless if you have it. If you can give me some info on where to purchase your products I will definitely buy this system or one suitable for my make and model bike. Thanks man
www.BrocksPerformance.com
You just sold me on your exhaust I'll be getting a predator for my zx10r
Great choice!
