"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!
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.
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 👏 🙏
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?
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.
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.
I’m not sure which one had the stepped exhaust. The first video sounded best to me. @Maisteer when I was at Goodwood after watching your videos I looked more closely at the exhaust of the pagani huayra r. It actually doesn’t use steps, but many different merge collectors. I think it’s 12-4-2-1 with a pinch point just before the exit.
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! ❤
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
having no musical background and some missunderstood physics ive finally had my AHH HA! I UNDERSTAND IT NOW! moment. all thanks to you. ill be spending the next year in the garage probably failing at putting this into a real life exhaust... thanks!!!
You've got me imagining a Trombone-exhaust that is automated to change lengths depending on RPM to get the perfect sound all the time.... if only I had Money I'd do it myself! I have the knowledge and I know how I'd do it- Time is the true enemy! *Really great vid, I thought I was subbed- well, I am now ;)
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.
Do you think adding a step up from 1-3/8" to 1-7/8" in the primaries shortly after leaving the head (6-10") and then another step up where the 1-7/8th slides into a 2" and then the 2" has a cone reduction back to 1-7/8th, would help that resonance increase and thus furthering the chase for the F1 sound?
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.
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.
interesting .. wondering if you could use coherent air pressure (like a laser ) from exhaust and modulate the separate pipes to tune it to its natural resonant harmonics. would need a sensor controlled malleable cavity, perhaps trombone style or values to other chambers? likely going to get something completely different and the back pressure will probably negate this.
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.
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).
All this exhaust header stepping makes me wonder how a stepped inlet manifold affects performance and sound. Still pressure waves present in the inlet as you've mentioned in previous videos.
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
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.
I don't understand. So what he is saying is that the step on the outside of the exhaust also makes the hight pitch frequency? @ 9:44 I noticed a big step on the 6 into one concrete header 😊
Not too sure if I wound put 6 undersized steps just too make it sound nice. Either it's different length pipes or 6 expansion chanmbers like a 2 stroke?
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.
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?

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.

This is genius. You should make an exhaust that bubbles up through water like a bong.

God i love watching a random car video and seeing people frankenstein'ing an m50b25 motor
this feels similar to someone playing around with oscillators until the right combination of things makes it sound good. shape, resonance, ...

Thats one way to Brick a motor.

Is it possible to get this or similar sound with a turbo? Perhaps stepped header, and then the turbocharger?
When u say stepped do u mean increasing or decreasing the size of the pipe or putting offset on the same size pipe?
Increasing it slightly, if i remember correctly
That is some concrete Stience!
