You guys do excellent work. Please keep making videos for us exhaust nerds!!! My dream is one day owning an S65 AMG and bringing it to FMU for a full exhaust ❤ and maybe an LC500 😄
Not at all the sound that I expected. I was thinking early 90s F1 car but we got 60s V12 Lemans prototype 😮
Sounds a lot like a Matra V12.
@@Flu_Tang_Clan exactly
@@SgtHenick sounds wild!
Not a bad thing at all!👍😎
So underrated! You deserve to be where the channels that do the cheap quick fixes are. But better, because you don’t do those cheap fixes.😂
Hands down the best way to learn about all the planning and craftsmanship that goes into that exhaust. You couldn't make a better promo. Thank God we got to hear it sing at the end haha
Glad you enjoyed it!
Very interesting sound. Reminds me of 60s f1 v12 sound
It does, doesn't it... Interesting
Sounds like wet farts that contain some iron filings
Silence to Violence?
Kudos to whoever dreamt that one up.
Well Done.
love the discussion and illustration, keep up the great work OJ
Are we gonna ignore the fact that hes also super jacked
Nope! 💪
Allegedly, He manually bends his own exhaust pipes by hand
@@fsujmm lol
A lot of commenters on the short didn't understand that a lot of aftermarket headers are designed to sound cool, at the detriment to power and throttle response. Short tubes sound raspy and rough, but it's easily what makes the most power.
I really appreciate the thought you put into the firing order and approach to the plan for the exhaust. While not as cool as a v12 I recently went down a similar rabbit hole with a 5 cylinder.
Would be great to see some more of the every day performance cars, I like your approach to explanation and how you don’t cut repeatedly while talking.
Thanks OJ and Team. For a beginner like me, I really learn a lot from your simple layman term about custom performance exhaust. Keep up the good work.
I found you guys many years ago from a teaser video of velocity stacks on an M5. Great to see more in depth content! Hopefully some more S85 content in the future
the megaphone creates a point where the exhaust pressure wave (that makes its way down the exhaust before the exhaust gases) bounces back to the cylinder which helps scavenge the exhaust gases away from the cylinder. without that megaphone, the pressure wave still travels back to the cylinder but much slower.
Another great one OJ and team. You're taking exhausts to another level. This is more like art than anything. Thanks for sharing your know-how on what is possible. A great sound makes the car so much more special. Except on my 4 banger turbo 🥴 keep it up 😁
17:10 PREACH! PREACH! Centerline to centerline and radius of curvature are SO important!
Thanks for showing us the thought processes that the team goes though on a project.
WOW!! That sounds and looks amazing!
I love the technical info! You guys do such premium work
That exhaust is stunning. It actually sounds a little deeper in the low rpm and and higher in the high rpm IMO than others.
Sounds really good at free rev. Gotta hear it on loud. Best sounding aventador I've heard so far.
It’s absolutely amazing. But I have the say. The only thing I don’t like is the exhaust note. Which is unfortunate because it looks unbelievable
Can't wait to see some drive-by vids, sounds very different to stock
This is wild. Work of art.
Great video! It's refreshing to witness a shop that not only showcases its products but also delves into its thought process, providing detailed explanations of the 'why' behind their choices. I've just bought the FMU hoodie, and since I work nearby in Lisle, I'll definitely swing by to pick it up in a couple of weeks.
Thanks for the feedback, and the support! Shoot me an email and let me know when you plan to swing by so I can make sure we are free to give you a tour! donny@fluidmotorunion.com
I love exhaust work it makes me want to study fluid mechanic
Interesting how people are comparing this to another exhaust, LOOK AT THIS THING. As a guy who loves to build "outside the box" type pieces like this...backed by theory... Hats off to you guys man. Ive been lurking you guys since like... I wanna say 2009 or something? Can still picture that e46 m3 exhaust with the vibrant ultra quiets in a blog post. So awesome to see how far you guys have come. Keep the videos coming! Cant wait to hear it actually picked up on the mic.
Great work guys!
Great illustration and content!
🤤 wow. Amazing work as per usual. Silence to Violence. Stolen to work into my repertoire.
Amazing work, ethic and problem solving!
Thank you! Cheers!
gave me an idea for my 89 camaro thank you
Amazing work!
that sounds insane
That’s a pleasant VROOM
Absolutely amazing
Thats sounds amazing
When's the dyno and the drive by video? (Love the vids!)
Looking forward to the dyno sounds. This should be good.
coming soon...
So did it make any more power at the same time as looking awesome ?
A great video the way you describe the thought that goes into the exhaust! The final product is beautiful. I love the H-pipe disgust. If you could only go back in time and rewrite all thise years of "an h-pipe is a good option if you cant do an x" in all the car magazines.
Nowt wrong with an H-pipe at all. Such snobbery may belie ignorance, or a tendency to follow trends instead of putting the effort in to learn and understand. In resonant acoustic terms, an H-pipe is a perfectly fine alternative if an X-merge won't fit or sounds shit. The "H-pipe disgust" exhibited here is marketing intended to lure you, specifically. I mean, if you were in the market for an exhaust for an Aventador in the first place.
X-merges these days are mostly to keep the exhaust quiet, anyway... and turn most engines into randy elephants when uncorked. They really don't flow any better than an H-pipe because the branch experiences no net flow. Careful selection of the H-pipe's size, location and length will yield excellent results in most cases - which is why Lamborghini used one here (also to reduce sound volume, again). Pissing in the wind with random parts in random locations will just result in piss all over your face.
In this case a complete misunderstanding of how each group of three exhaust pulses sounds in its separate collector (just prior to the stock cats) ruins the overall effect. Lovely pipework, but it only accentuates the slightly dry tone of the Aventador (like the E46 M3 problem, doubled). Obviously a loud exhaust is automatically an impressive exhaust, and everyone knows that perceived sound quality doubles with every 3 dB increase in volume. And buyer's remorse will prevent any bad press.
Instead of chatting shit about airflow, if someone really wanted to change the game, they'd ought to make some performant and sonorous headers for this engine.
Theory matters very little if you can’t fit it into a cars constrains, which is why manufacturers end up leaving power on these cars despite having the best engineers in the world. This is all just internet talk till YOU design, build and test one.
We’ve been building exhaust for 16 years, and quite simply, we hate how H pipes sound.
Tomorrow when the video drops and the power gains are shown, everyone will rush to make something similar, and all of a sudden people won’t be comment about “exhaust pulses” on our videos anymore. Please drop by tomorrow at 9am!
@@FluidMotorUnion obviously I wish everyone the best of luck when such blanket statements are involved.
I appreciate the encouragement, too, thank you. Unfortunately I'm unlikely to be able to put the time in to match even a novice fabricator's ability, so you won't ever have to test that assertion.
It's not hard to make more power with a less restrictive exhaust. Unfortunately, that's not legal everywhere and is why the engineers get paid so much to "leave power on these cars".
If your system is so much better than other aftermarket designs, I imagine you'll be comparing it back to back to prove it. I might not "tune in" but I'll certainly ponder what revolution you guys could possibly have been cooking up that is beyond anyone else's fathoming. Especially an engineer ;)
All i know is the tube lenth is determined by keeping the pulses from each cylider crashing into another.tune by firing order essentially.Equal lenth or whatever fits causes pulses to collide. Anti reversion chambers at the colector helps, too.
Would you have made more power by prioritizing length vs aesthetics?
I truly don't understand the science or engineering, but damn I'm learning, great content.
Colin from South Africa
Boy that is so complex. Great job.
There is very little engineering and science here. This is using his anecdotal experience to create what he considers optimised geometry. If it was actually engineering there would be more math and fundamentals being applied.
@EnlightenedSavage watch the full video
don't vortexes help only when theres a vacuum behind the outlet. Would that not reduce back pressure then?
Oh man, this is quite some display.
I mean. You guys did it again😂
Would a double x pipe have worked above the top of the collector or does this intersection make a terrible disruption. So if 1 crossed over to 2, and 3 crossed over to 4 the it would
43
12 from above counter clockwise
This guy was meant for the camera.
Also, how humble of him not to show off. We all know he bends those pipes by hand.
The grip strength is immense.
No matter how challenging things may be, it is always about discovering. What can be done, how it can be done, being able to study the knowledge you learn from previous experience. Now the best part rewarding yourself with the hard work put to play at FMU. Always keep it up and never be afraid to let your ideas come into reality. They typically end up working out better than we normally think. Good job guys at what you guys do sincerely.
Ahhh i wish i could remember where i saw it(instagrame) but it was a wicked 4/1 collector with had a 90 degree helical in it in it .. wopuld have been great for this ..
That is the most wild looking Aventador exhaust on the planet! Was great hesring about all the theory behind the design, definitely has a unique sound but want to hear it under load.
No odea why the customer would want to leep cats on it, seems a waste to spend that kind of time and money on it and then keep cats on it.
He's so smart. Would like to chat in person about car nerdy stuff!
Exhaust is a fucking black art. A good exhaust is one thing. A GREAT exhaust is something else entirely.
Nice!💯💪
I thought of this 12-4-1 idea a year and a half-ish ago. Glad to see another braniac figure it and and then actually MAKE ONE like a proper badass. Wish I was exactly the man you are because I'd be out there making cool ass shit instead of moping about the state of the world, never getting started, and living vicariously through youtube.
A point of critique, though: Since it doesn't sound as high-pitched and smooth as I thought it would, I think keeping it simpler would've been better. I 100% would've nixed the megaphones and put the cats where they "should" be, and I also 100% would've made the final merge at least a 4-inch if not 4.5-inch or some kind of circle into oval thing.
Also, one thing of note, the Lambo V12 to my knowledge is a shared crank pin 65-degree engine, so not QUITE even firing, which means a full equal length between each side's bank of 6 isn't exactly even. You kinda need to delay/bias one side a bit to even them out. However, you'd have to talk to David Vizard or some other type of legitimate physicist/engineer to figure out how much exactly.
I assume there is no power gain so what is the difference in the noise? The v12 in the Pagani sounds like the old 1990s F1 but this exhaust sounds the same as factory.
Nice. Aventador S tuned with exhaust should make 680 wheel hp and 500 wheel tq
maybe you compensate those pressure changes from the different turns / lengths / straightness pipes using your trumpets …. of which size, ya, you need some physics to help. but ya, put a trumpet into a straighter section pipe to adjust the pulses so it pressurizes at the same volume as the more bent pipe. maybe?🤷🏻♂️
Just wondering, will the cats run hot enough ?
You could have two pipes up and two down . The collector could be cut turned 180
I’m not a car guy. But my mind is blown.
Damn you can tell Cody is master craftsman it really amazes me how people can take things and turn into performance art
Here before the titles is fixed
I expected it to sound like 90s F1 car, or at the very least, better than an Gintani exhaust......how can something be so awesome and complex, while sounding like $#!+
Has anyone ever made a spiraling merge collector? Like if each of the merging pipes was twisted at the same angle. I'm not sure how this would affect airflow or performance.
This was my first thought as well. If you twisted it just the right way, I think you could get a perfect spiral for all four banks.
Sounds mean!
Could you have rotated (twisted) the collector 90 degrees and not have to crossover. Meaning if you were looking straight down on the collector it would be a diamond vs a square.
Draw it out an try it, it just makes the other pipes more complicated and you can’t avoid the cross
Dyno?
To prove the concept, you should do a comparison without the 3-4 crossover.
Is possible to make a b58 supra sound good?
Absolutely! We have an exhaust recipe that will extract a clean JDM sound. Shoot me an email to get started! donny@fluidmotorunion.com
Not as high pitch as gintani but my god that sounds brutal
Wow
Great video and quality, only feedback i could give is talking a tiny bit quicker…
Does FMU ever work with titanium or inconel?
FMU has the abilities to do both, yes.
Yes sir! Most of our customers opt for stainless due to the cost, but our fabrication department can do titanium and inconel as well.
@@FluidMotorUnion what do yall think about the new tech that can 3d print inconel exhaust systems?
why is this dude so jacked
from lifting car parts
@@FluidMotorUnionLOL
I wonder if @thehamiltoncollection saw and heard this and made him rethink the gintani exhaust he got for his aventador.
Ok so help me out plz. Everything i have ever learned racing V8s, and seen with testing, a 4-2-1 style exhaust is the best way to go. You get the best Exhaust Scavenging, as well as good tuneability when done properly. I am confused how this would be better. Especially having that small of an outlet. Exhaust back pressure is not anything you want unless you are trying to spool a big turbo with small engine. I guess im bot understanding this design personally.
4-2-1 being optimal is if you have unlimited space (tube frame race car). We go over this in the video, but you are never not dealing with space constraints on a passenger vehicle. You can NEVER, have optimum exhaust routing unless you built the car around the exhaust. Every turn, bend, weld, reduction, expansion and chamber effects flow characteristics, as well as thermal emissivity. You basically pick and choose which vectors you want to attack for gains, and test if it makes improvements. You can have all the formulas in the world but if it doesn’t fit in the car it doesn’t matter. This is also how manufacturers build exhausts. They have more restrictions on sound and emissions levels obviously. Rewatch the section where we talk about constraints and have to test for a more complete explanation.
@@FluidMotorUnion .... hey buddy, i watched and understand all of that. I work on and build All out Drag cars over 2000 hp. Again, i go back to very small piping for something you expect to put power adders on??? You will see some serious back pressure anytime you add and sort of air flow. Not saying your exhaust is bad by any means. I like your stuff. I think you should be more accurate when explaining this. I think you should not be leading ppl to believe putting a small diameter pipe will increase HP. That's dead wrong. Yes EVERY DESIGN HAS RESTRICTIONS. THATS CALLED ENGINEERING. I like your design, and enjoy your vids. Im very happy you explained this is not for sale. Or at least to the masses. Like you said, it doesn't make sense for most any vehicle. Im going to assume you know what im saying, and aslo you use Pipemax, or sum other software which taught you all of this already. But youre talking ab Space Constraints and making a freaking exhaust 8 ft long! The reason you see power incrwase is EXHAUST SCAVENGING, which you understand. Well, that goes away a lot as soo. As ypu bolt a pressure making device to it. When adding a Supercharger, its all about getting EXHAUST OUT. Same with a turbo, to a certain degree, post TURBO anyway..........Anyway. Unfortunately, youre still misinformed. Hopefully you will see that its very misleading thats all. Maybe not and you will keep teaching WRONG SHIT.
@patrickoleary6379 nice you wrote all this out. Here’s the video released today. czcams.com/video/7ScsSB4NHfk/video.htmlsi=DitZ1IqGZIV-_zrx it basically address everything.
😮😮😮
Gintani's already done it and it sounds better....
Amazing But Gintani's STILL is higher pitched F1 sound
We couldn’t gain out the mics to match the levels. Video doesn’t pic it up, it just sounds distorted recorded. It was a big factor in why we cut the video… we bought some new equipment but it will be correct, and under load next video. Sorry we’re just little guys in the video world and handle the issues as we run into them.
@FluidMotorUnion Thank God 👏👏👏 Respect for the engineering and thinking outside the box. I cant wait to hear the exhaust properly.
Jesus, if you're burning out mics that's a good sign LOL
No Batman intro. 😢
🦇 🧍♂️
i prefer gintani F1 exhaust, your exhaust look cool but the sound is muffled for me
Love your videos and experience but for God sake combe your hair 🤣🤣🤣
If you want a scientist knowledge contact me i will give you solutions to all your problems!
The reason I'm doing is because i haven't see a proper exhaust system and i want to be a part of this just because i like your work.
No money involved just my name to be mentioned!!!
Does it miss the streak to anyone else or is it just me?
No, the sound isn’t good. Our mics cap at 100bd and this is close to 120. It’s just comes off messed up over the levels. We were not prepared for the intensity of this thing as we are a little shop, not well versed in video production yet. We had to buy sound equipment and push the next video release back cause we know this is going to blow people away.
@@FluidMotorUnion fair enough. I like how you explain the concepts behind the build
Looks good but sounds terrible.
Lol yeah sounds awful.
Lol sounds like a chainsaw 😂
Lol that sounded crap im sorry
now hang a turbo on it ...
Or four...along each 3 cylinder "bank" just before this exhaust. It would sound INSANE .
Well ive got a full exhaust and air intake( new charge cooler ,rads,oil cooler for my F80 M3 and its by far the best money ive spent on it.
