Why do people ask to like and subscribe at the beginning of the video - do you review the restaurant before you eat the meal - that is truly 'Baffling' to me - otherwise nice video and I have 'liked' and subscribed.
@@DennisKirk I guess it makes sense then - youtube is a mysterious land that’s for sure - keep up the great Videos.
@@DennisKirk Don't expect them to sub before you have provided any value... Intro like this is also why most people dont go past 5 sec mark
@@madmangaming8751 We appreciate the feedback! We hope you can check out some of our latest content, where this has been eliminated, and we hope this video was able to help you out if you made it through!
Exactly.
you're still in the past
Ordered plenty of things from Dennis Kirk over the years, never had a single problem with them, one of the best bike parts places out there.
We appreciate you and your business, Billy! Thank you for the kind complement.
Good to know 👍 currently looking for some stuff myself
For me, its not about getting quieter, it's about removing reversion and getting my Torque back. People weren't joking when they said some aftermarket exhaust changes your powerband. Sure my HP/Torque probably is same, but you REALLY feel it slack on the low-midrange RPM without Baffles. I popped one in my bike and boom, she rode smoother than ever and got a richer tone.
I agree with you, bladed.
It really depends on the bike and the exhaust system.
I had drag pipes on my shovelhead and just put some pipes with mufflers on it and experienced what you said. It's smooth all the way through and feels like a new bike yet still sounds good.
I have two baffles on my exhaust muffler tail end came with it and I added honey comb baffles in front of muffler try make it more quiet! The muffler came with my was to heavy and had a crack on it so I replace it with a Istunt muffler because looks great but makes popping noise when driving down the roads!
wow great transition of knowledge
Hye i just got my bike gixxer 1000. so currently im using yoshimura r11. my mechanic suggest me to open the muffler. removing the old fibre. then a solid pipe is inersted into perforated pipe while the ouside is wrap using new fibre (in your video the left one). the sounds is great and sharper. do yo recommend this? THANKS A LOT.
So technically, the term back pressure is wrong but also right!
A small obstruction that does not increase back pressure will produce more torque and horsepower in mid and high rpm ranges on any 4 cycle engine.
The Reason?
Valve overlap. The rushing gases exiting the pipe keep the exhaust moving at high speed thus actually sucking more fuel and air into the motor with less spent air remaining in the cylinder. We have used lollypops many times in the past and welded simple washers into pipes to improve takeoff speed.
Great for mid range power on the street.
The great side effect is it runs both cooler and quieter when you want or need it to 🙂
Thank. You. Back pressure is a byproduct produced by the bends and such in the exhaust system, which are needed to aid in exhaust gas scavenging as you said. Back pressure isn't a "needed" thing like we've heard from so many people over the years. It's just an unavoidable byproduct of any exhaust system because physics is a thing that exists. You ideally want an exhaust that scavenges the most gas with the least amount of back pressure possible at whatever rpm range you need
Did you solder the washers in the end of the mufler or in the start of the pipe?
I’ve got V&H Big Radius 2-1 and it’s too loud for me. V&H says they don’t make a baffle for it. There mus be a way to bring it down. Any thoughts on that?
I've tried all kinds of different ear plugs, on the bike. Time to figure out a baffle. What got me here is wanting to make an insert for my car, tired of wearing earplugs that don't do enough. Too loud.
The most nasely explenation ever! Great thank you :)
I definitely need something for my bike. I got a sv650s as my first bike and it has an aftermarket exhaust and it's so loud. Lot of low end from it. I was getting lessons and couldn't hear the instructor over the Bluetooth radio. I tested it out putting a brush handle in the exhaust and it still had the nice midrange grunt but it reduced the low frequency and it helped a lot.
What did you do in the long run? I just got a Suzuki gsxr750 and it’s so loud and I can’t hear ppl over my mic and my music constantly battles the exhaust sound lol
@@eclipseshadowyt5917 i got a XS650 with straight pipes, i think i might go with the middle one he was showing to cut that noise down just enough to not wake the "entire" neighborhood.
If i need a deep V2 sound not insane db just deep sound on my Kawasaki VN800 what kind of baffle or procedure would you suggest?
Nice video man, very informative. just a quick question, I'm trying to quieten my exhaust but I have a baffle that's short like the one on the right. However it has a cap on the end whilst that one goes all the way through. Can I still wrap this baffle or will it suffocate it?

Just bought a 2005 Road Star 1700 that has Harley Thuderheaders 2:1 installed. Looks awesome but a bit loud for what I"m looking for. Any recs (if possible) to quiet it down?

Thanks for posting. It is well worth the time to watch. Loud pipes don't save lives. Properly trained motorcycle riders, saves lives. Loud pipes are what is getting a lot of really good motorcycle riding roads, closed off to motorcycles throughout Europe. Spain had banned bikers from some of the best mountain roads in that country, and it is all down to loud exhausts.
How long does glass packing typically last? Does it outlast steel wool type packing?
I haven’t ordered it yet but thinking of getting one of the shorter baffles (the Q7 stage 1) for my M4 GP exhaust and eitherwrapping it with steel wool or fiberglass but poke openings in two of the holes for “breathing” Would that cause any issues? Open for suggestions, and bike is 2012 R6
That is a great question! Our tech team will be able to give you the right answer - give them a call at 800-969-7501.
My biggest issue on my 06 streetglide is when I pack the Vance and Hines 2 into 1 exhaust it sounds good for a couple days but eats the wrap out fast . Probably just going to get a quieter exhaust
Wow👌
is it ok to ride a motorcycle without a baffle..just the open exhaust? When I had a baffle there was a little crackling and back fire...but once I removed it, there was not crackling or backfire...but I don't want to ruin my engine, so just wondering if its ok to ride without it?
It is okay to ride without it. It will be louder.
Hi great video, I have a westfield Kit Car with a 1.8 miata engine which has a noise test it was 103db and it has to be 99db or under would fitting the centre baffle reduce it enough.sorry its not a bike question.regards Dave

I'm fixing up an 1984 Honda v65 Magna, but the previous owner took the baffles out of the mufflers and now I can't ride her for more than an hour without my ears ringing; do y'all have any recommendations for baffles that could quiet her down while keeping the stock muffler shells?

I have a question, im from switzerland and it seems like not many exhaust are legal here, but im not sure what exhaust fit on my GSXR 600 k6, are the exhaust build for a specific bike or can i basically just slap any slip on i find?
Great question! The slip-on you choose has to be compatible with your exhaust but there is a bit of wiggle room. Contact our tech team at 00-969-7501 - they'll make sure you get the best answer and that you get pointed to a couple of products that could work for you.
I have a diesel John Deere gator. Thing is obnoxiously loud. Hopefully I can get something to quiet it up
If I were to cut off the entire pipe part of the baffle only leaving the little part that screws into the exhaust would that make it louder?
For example cutting off the entire pipe part with the holes in it
That is an interesting question, Xalon. We think our tech team is going to be able to give you the best information, and if that is actually a good idea to achieve what you're after. Please give them a call at 800-969-7501
It would make it louder but it might have a bubbling sound to it and whenever you adjust a carbureted motorcycle you definitely wanna rejet the carb to avoid risking damage to the exhaust valves.

Hey guys, great video!
I have a question is it bad if you wrap a baffle TOO much ? I did mine to reduce noise as much as possible, but the air has to pass through the wool now, there is no clear path for the air too take. Could it cause too much backpressure ?
yep there can be to much so look out for stuff like this The classic symptoms of too much backpressure include things like a lack of high speed power, poor fuel economy and even overheating. Anything that backs up exhaust pressure into the engine will also back up heat.
@@DennisKirk Thank you! I'm also having some backfires when engaging the clutch when passing gears.. doesn't that indicate too low backpressure on the opposite ?
@@Baaconstrip Can be lots of things. maybe try a more breathable material.. Using fiberglass The material is thick and cannot breathe so well so try something like steel wool the air should be able to escape a little bit better...
@@DennisKirk thank you!

Hi guys,
Just purchased Cobra slip ones for my HD 2018 lowrider. Delivery was quick and the slip-ones are of excellent quality. However they are for our place (Korea) a bit too loud. Which quiet baffles can I install/order? Not sure about the right ones, when I checked your webpage. Thanks for a reply 👍🏽
call customer service they can help you out! :) 800-969 -7501
Dennis Kirk, Inc, due to time-zones it is pretty difficult to call. Wrote already to the Service. Their reply was: we do not have, I should write to COBRA directly. I did, but they do not reply.
Please help. Thsnks!
@@sammspeed okay what is the year, make, model of your bike what exhaust do you have on right now? model number is needed
Dennis Kirk, Inc. , Hi 👋 the bike is a 2018 HD (M8) lowrider. I installed the COBRA slip ons from you, ordered according to the model list in your webpage. As mentioned, they fit perfect, quality is excellent. Only issue is they are for our traffic laws a bit too noisy. Since I can look completely through the slip ons, I was wondering, whether they are quiet baffles available for that slip ons as well (as they are for most COBRAS and V&H) etc).
My order number was DK120-0813-404-3915819
Thanks for helping 👍🏼👍🏼👍🏼
So I asked around and you seem to have gotten an exhaust pipe that we do not have a DB killer for as the name of the pipe suggested its a neighbor hater for a reason. I am sorry you can always try one of the DB killers on here BUT SIZE IS HIT AND MISS as it's not specifically for your pipe. www.denniskirk.com/search/cobra+nh+baffle.q
👍👍

Make video on how to install each one of this
I know this is an old video, but I just found it.
I saw that you mentioned on the “mid/intermediate” range baffle that the interior of that baffle gives a characteristic sound. What would it sound like ? Would you have any video showing it ?
Thanks.
Great question! We do not have a video currently, but let us see if we can hunt down something for you to take a look at.
I would like to see that, too. Thanks. (Its a bit "baffling" why this video does not end with, nor include SOUND examples of all 4 types: Unbaffled, THEN the 3 types of baffles shown. - I am also looking for "how easy is installation" video. Seems to be missing from everywhere. Everyone days "its so easy"... yet no one shows it. Is there drilling or not. etc.
Found a video of "installation"... Not perfect, but shows there needs to be a HOLE at the bottom of the pipe, to fasten the new "baffle" in place. That's the info I was looking for. czcams.com/video/0ckqgE92xZE/video.html
Touching fibreglass with bare hands big brain time 😂😂😂😂😂
It's true the fact that if you remove the baffle the bike will do that popcorn sound?
it will be loud and possibly will crackle
my baffles sheared on my rpugh craft exhaist they were on the bike when i got it emailed em no reply amy recs for this type exhaust its really short but am pretty sure baffles were 6 or 8 inch i just wamt thw same sound back

@@ironkid8836 hmm well you might just have to test out some to find the sound you are looking for. but bmosher@denniskirk.com might know tell him Dylan set you
What kind of tape did you use?
The tape on the baffles is the tape that it came with out of the box.
I cant find the baffels on your website to harley iron 883.
Hey Jasper! Please give our Tech Team a call at 1-800-969-7501 - they should be able to point you in the right direction for a baffle that will work for you.
I'm so baffled.
Does keeping baffles on help with mileage?
Don't know about bikes but I put a 2" pipe/cherry bomb exhaust on my 1990 Ford Festiva and went from 52 MPG to 45 MPG. Lucky that I saved the original exhaust.
How can you expect someone to like your video before even watching it? Whats the logic behind it and what if I don't like it? At least, you got me to write a comment. You're welcome.
Thanks!
But Dennis, what about earplugs? Do they help...?
yeah you but its still illegal to have too loud of a motorcycle.

@@DennisKirk thank
How to make my motorcycle 0decibel, I want it to be silent.
Go electric!
M8 creates back pressure at the cat then splits to duels with more flow so how can baffel be anything but a muffler?JS
You're technically not wrong. Basically a baffle is a muffler, just without a case. All three of the designs show here are pretty much what glasspack mufflers for cars have looked like in the inside throughout the years. The last one with louvers inside is very old school, like 50's and 60's style, while the one with fiberglass around it is essentially the same design as a straight through muffler you can buy today from Magnaflow or Borla. The middle one looks like the inside of a cheap homemade suppressor. While that design doesn't work very well for that application, it works pretty well for a muffler baffle insert
Wow Harley's are quiet. My Suzuki RF900 is 105 at idle lol been looking for this for years!
Back pressure never equals horsepower. Wny propagate myths?
a little back pressure is a good thing. The right size pipe is large enough to breathe well but small enough to create a high exhaust flow. Steps in the exhaust system also create negative pressure waves that travel back to the cylinder and help empty the cylinder of those gases.
@@DennisKirk Why do you believe back pressure is good but then describes scavenging and negative pressure which is the opposite of backpressure. I'm tired of hearing this old wives tale when the proof is literally everywhere.
Back pressure is used to broaden the power band. Open exhaust or baffling does not change how much horsepower an engine will produce. That is just front bar bs.
@@madeleyinc please never repeat that utter garbage lie ever again.
@@DennisKirk back pressure is never a good thing. Scavenging is

Loud pipes saves lives .
Very informative but no helpful ways of packing or fitting 🙄😕
Thank you for the feedback, Adrian! We'll remember that for next time.
Spit on it, slap its ass, degrade it, then slide it in. Easy.
The only thing that hurts my ears, is listening to guys like you using a harley as an example, when in reality so many Japanese bikes make more noise when you get on them, how about power robing db reducers ,like the last one you showed, anything would be quiet it you restrict that much, right.
Great perspective, Richard. We feel that this got the point across regardless of the bike used, but maybe we can do a more metric centric example in the future? Stay tuned.
@@DennisKirk i will, always into testing. It's the only way to get it right.
I would be curious to see if a chambered silencer would work in this application, such as 69 camaro z-28 chambered exhaust.
Loud =/= safe.
Maybe when the best gear was leather jackets and when cars were full metal. Modern cars with modern families aren't going completely notice your sawed hog screamin because why would they? They got music, audiobooks, tv shows >:(, people they're talking to.
"Just be" a better rider that's aware that everyone is never looking,
good advice!
Backpressure isn't a thing. It's a made up term. Engines need scavenging and velocity and need less reversion.
@ 2min... and you are causing damage to innocent bystanders ears as well.

Three baffles, one demo. Which one? Sorry, thumbed down. Do it again and do it right.
Demonstrated a baffle, not these particular baffles Perhaps you missed the point of the video baffles will do the same thing They muffle the DB levels. Large baffles are quieter than little baffles.
