"No Officer, it's stock. Actually, it weighs a little more than stock". As a former audio technician and a hifi/loudspeaker enthusiast, I was going to commit the sin of commenting before watching with a big spiel about how it sounds better because the density of the material greatly reduces internal resonances along the length of the exhaust tract, which means that more of the energy in the exhaust gas is being contributed to the exhaust note instead of being wasted as heat, and the tone is much more dependent on path length/shape rather than resonance tuning... but you very neatly summed that up in the first minute. Cool video!
First, it was cow hoof repairs, then watch repairs, then MRE testing, then hydraulic press crushing now exhaust manufacture Thanks and yes this is what yt is designed for 👏 🙏
Well as somebody who has made some instruments out of PVC pipe, I can tell you that instruments made from PVC pipe sound unmistakably like PVC pipe. The material does affect the sound.
This video will forever be one of my favorites on YT. The science of sound. Can't wait to use this research one of these days when I've got the cash. Thanks a lot for your work.
Wow that sounds so good great work maisteer, how about a 6>3>1 header with 1-6, 2-5 and 3-4 pairing in theory having 3 360° twins merging into the Y-pipe instead of the usual 2 3 cylinder split would it have significant impact on the sound?
Very creative content. Even that shop set up is interesting as heck. Never seen garage doors like those. Seems like the kind of place you wish you could go, hang out and design and develop crazy stuff.
So we went from trumpet references to the exhaust trombone, and I'm only 6 minutes in. Since woodwind instruments use a special resonator in the mouthpiece - how long until that features in the exhaust demo :D
The tape was ideal for me, I can see where tape holds it's value by the "reel" enthusiasts out there. (Sorry for the pun) But I did like to see vinyl holding its own and also having a different listening experience which is why I decided to start collecting vinyl 👌 This was an amazing video, thank you! ❤
This project is your Ahab like quest for the white whale of supercar exhaust sound. I think I'm going to buy the extra videos because this is fascinating and must go on. I already dug out one of my SAE texts on manifold design and started watching sport bike exhaust sound videos to try to notice differences in design. The stepped or tapered pipes tend to have more of the sound you are looking for. Interestingly, all bike headers mispair the cylinders 1-2 and 3-4 which is different than the typical 180 degree pairing typically on 4 cylinders. I do notice a different sound quality on my 4 to 1 air cooled VW when it has a megaphone attached.
On a side note your thick accent sounds like you could be from near Thuringia. Yet there is often a hint of Swiss or Austrian. Very interesting. In Gera haben die immer so einen tollen Akzent.
I'm on this journey with you to learn as much as I can about exhaust sound. One day maybe I can make the BMW K1600 I6 engine on my bike sound as it should. A 1600cc inline 6 with an 8500 rpm rev range should be able to sound really cool.
Are you sure the 1M bmw has an 8 into 1 collector? I think it has 8-2-1 setup. I thought I saw a picture of it once with the 2 pipes merged near the rear.
Hey, if you need a 6-cylinder with similar rpm that's a 6-to-1 to compare with, this is the old Formula Renault 3.5 V6 (Yes, there was a V6 version, it wasn't always a V8): th-cam.com/video/QchT3bQjgp0/w-d-xo.html From what it sounds like you're definitely on the right track with stepping the pipes. The car's taking a very similar note to a Formula Machine with the same cylinder/rpm. Also that V16 Peugeot is also a 16-to-1. What makes this crazy is the fact that Formula 1 V8s were 8-to-2, with the high pitch obviously coming from the high 18k-19k rpm. That's why Hillclimb F3000s with a 8-to-1 (You can easily tell the apart from the other 8-to-2 F3000s) could sound similar since they double the frequency from their 9k rpm motor by collecting all the waves into one pipe rather than two. The Peugeot V16 on the other hand can achieve twice the frequency of both the 8-to-2 F1 V8 and the 8-to-1 F3000 V8 at the same rpm as the F3000 cars, and would sound similar at half rpm. That's why it gains that high RC Car-esque whine because the frequency is equivalent to a Formula 1 V8 at 36-38k rpm (Twice the frequency for half the rpm. Genuinely Absurd when you put the mathematics behind it). That also means if it revved to 18k like an F1 engine, it'd sound like an 8-to-2 V8 at 72k rpm, and god forbid what cacophony that would create XD
Here on YT someone is working on a pretty detailed engine simulator and that includes exhaust system sound. I think 2D version has been completed and now 3D version is WIP. I wonder how it could be used by someone who actually has some idea about engine exhaust design.
Ceramic coating inside the pipe will help keep EGT higher , same with wrapping the exterior of pipes. Wrapping will add small amount of mass to the pipe system which could slightly shift the resonance frequency

Waiting for the video where you start with one step up in diameter. Then two steps... then three... then 5... then 8... then 12.... I mean... what would happen if you just kept adding step ups in diameter right? What could possibly go wrong?
no, on the other side it can go back to the initial diameter if desired. the whole purpose of the steps is much like that of the inflection points/y pipes: it reflects a pressure wave essentially multiplying the force heard which is necessary for that screaming f1 sound. he explains in another video how a proper spaghetti exhaust system made to have the pipes connect in sequential order around the collector along with high revs completes the sound. heres the video in case you missed it: th-cam.com/video/vA-Z3ncTdUY/w-d-xo.html&ab_channel=Maisteer
If you check any videos of the cars in pits, you can see that they also use stepped headers. Considering the high pitched nature and what Maisteer showed in this video, they all use some form of stepped 6-1. Quickly searching for pictures I couldn't find any that reveal the full system but then searching for BMW M1, it also reveals that the ones that produce high pitched "race" sound use stepped 6-1 headers (probably with some form of intermediaries as Maisteer has shown).
It kind of sounds like the sampled and simulated audio that something like beamng might use or any racing game really that dynamically creates the revving sounds idle notes .etc. the concrete seems to isolate any errant resonance or rattles that accompany the acoustics of live vehicles just leaving its pure tone from its timing and pipe dimensions
Germany, the industrial engineering capital of europe where also bach and beethoven are from... yeah this guy knows what he is talking about when it comes to the art of beautiful engine sounds.
Hey prof! Can you talk more about how to make inline 4 to have F1/ motorbike(YZF-R1) / LFA sound? I really love that kind of sound with 4A GE or 3S GE😍😍😍. The similar video of sound you can find from Larry Chen 4AGE Formula Atlantic page. It's a good reference.

To be fair, theres a difference between making instruments out of PVC pipe, and making an actual instrument out of shaped PVC
You slept through the part where he said human mouths don't rev to +7,000rpms and create pressure enough to vibrate the material ITSELF.

God i love watching a random car video and seeing people frankenstein'ing an m50b25 motor
This is genius. You should make an exhaust that bubbles up through water like a bong.

Very impressive research. One my viewers put me on to your channel and it gives me insight into why my Ferrari engine doesn't sound like a Ferrari.
I have been waiting so long for an upload and hollly mollly Im happy he did.

I'm impressed by your dedication to solving this physics problem. Or is it a musical problem? I think you're very close to finding the solution.

this feels similar to someone playing around with oscillators until the right combination of things makes it sound good. shape, resonance, ...

Side quest: Can you made an unequal length header for an even firing inline 4 (180-180-180-180) to sound like a cross plane (180-90-180-270)
Is it possible to get this or similar sound with a turbo? Perhaps stepped header, and then the turbocharger?
your neighbours must love you haha
