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.

That exhaust is stunning. It actually sounds a little deeper in the low rpm and and higher in the high rpm IMO than others.

[@onnovannoort7690]

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 😁

[@cuttingedgeinnovationstati5208]

Thanks for showing us the thought processes that the team goes though on a project.

[@jtalweezy]

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.

[@AtlanticBuilt]

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.

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.

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.

[@SweVikingRC]

So did it make any more power at the same time as looking awesome ?

[@bl78ljb]

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.

[@identiticrisis]

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.

[@FluidMotorUnion]

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!

[@identiticrisis]

@@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 ;)

[@Mastermindyoung14]

Would you have made more power by prioritizing length vs aesthetics?

[@identiticrisis]

Oh man, this is quite some display.

[@arcadiagreen150]

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

[@Khoolhwhip]

don't vortexes help only when theres a vacuum behind the outlet. Would that not reduce back pressure then?

[@jasonhumphreys261]

Looking forward to the dyno sounds. This should be good.

[@FluidMotorUnion]

[@Portaportoopoo]

[@redstang70]

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.

[@aldoc.4288]

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.

[@____MC____]

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.

[@Drunken_Hamster]

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.

[@kensutherland414]

Just wondering, will the cats run hot enough ?

[@pomanprod]

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.

[@spdcrzy]

Exhaust is a fucking black art. A good exhaust is one thing. A GREAT exhaust is something else entirely.

[@Deathignator]

Here before the titles is fixed

[@reedjacksonmaccom]

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?🤷🏻‍♂️

[@alextasarov1341]

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.

[@spdcrzy]

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.

[@psPio97]

[@-eduarth_ab6693]

Is possible to make a b58 supra sound good?

[@FluidMotorUnion]

Absolutely! We have an exhaust recipe that will extract a clean JDM sound. Shoot me an email to get started! [e-mail]

[@topnotchtsi]

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.

[@FluidMotorUnion]

Draw it out an try it, it just makes the other pipes more complicated and you can’t avoid the cross

[@justinwebster7761]

Damn you can tell Cody is master craftsman it really amazes me how people can take things and turn into performance art

[@lanceboyle4255]

To prove the concept, you should do a comparison without the 3-4 crossover.

[@patrickoleary6379]

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.

[@FluidMotorUnion]

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.

[@patrickoleary6379]

@@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.
