there wouldnt be much there tbh, white smoke is water in the engine.... but here its just hot air coming out into the cold temerature. kinda like how you breathe out an fog cold windows...
in actuality, having the exhaust of all the cylinders sync reduces the sound since the peaks and valleys of the pulses cancel them self out, after you can add a chamber that tunes the frequency lower, say a 3rd order, then the resonator to reduce the remaining high frequency and the droning and finally a single muffler to reduce the overall sound, the entire system, would be one resonator and 2 mufflers in series tied to a heather with an expansion chamber to lower the velocity before the resonator. practically complete quiet and much, much less bulk.

The quieter the car becomes, the more back pressure it has, which is not good for engine's performance. I guess if you want a very quiet car, you can have many mufflers, if theres enough room underbody to fit them. The less back pressure, the better the engine's performance. Better the engine's performance, the better the drive. Also the fewer bend(s) the exhaust pipe has, the better, since there is less restrictions and less time delay getting the exhaust fumes out, and that's a good thing. The best bend(s) is no bend(s) at all, but if must have the bend(s), make sure its mandrel bend(s), mandrel bend(s) is the 2nd best type of bend(s). Bend(s) to the pipe adds back pressure and more delay to the exhaust fumes coming out.
@@theroyalcrownedtiger2946 Engine needs a certain amount of backpressure. Expecially the low compression motor. But of course, what he did there was ridiculous lol.
@@RideOrangeKTM 4 stroke doesn't need back pressure it needs exhaust scavenging. Check this video out ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-A2G1EOB4P3w.html
Wow, an ultra-wide video! Not even the largest channels can get this one right. It's amazing to see how the production quality has improved over the last 6-8 months. Keep it going guys, I look forward to seeing what the future brings for this channel :)
The Bushwacker oh, its on one of those little gyro mount thingies that remove all shake from the camera, his hand is moving a fuckton meanwhile the camera is smooth via.... well i dont really know, but you can google it. Just look up “anti shake camera mount” or something
He totally missed that a lot of noise is being emitted from the intake. A lot of newer cars have a resonator built into the air cleaner box. This older car in the video has a very short distance from the carb to the cylinders, resulting in more noise. They should’ve mounted mufflers to the intake as well
@7:32 "If only everybody would drive around with a similar system. You wouldn't hear the cars coming." - The pedestrians not hearing the cars, and the drivers not seeing the pedestrians. Sounds great!
Routing cylinders to separate mufflers will worsen the problem. When you have one muffler per cylinder, you have massive short-term pressure increases within the muffler. Since sound is essentially pressure variation, these sudden huge jumps in pressure will be very noisy. I.e, you need to keep the pressure as consistent as possible to reduce sound. Mufflers try to even out these pressure spikes with internal baffles to reflect and disperse the pressure wave, but there's only so much they can do. You need to do the best you can at the inlet to the muffler. Routing all cylinders through a single muffler creates far more consistent pressure entering the muffler since the exhaust strokes are staggered and therefore the pressure spikes are more frequent giving the overall pressure less time to decay and thus less pressure variation on the next exhaust stroke.
i am not an acoustic engineer but this kind of thing fascinates me. i think doing a header into a single exhaust with 2 (or 9) mufflers would have been quieter.
2 years ago, I connected my garden hose (30 meters long) to my Honda CBR-600's exhaust. It sounded like a 50cc engine at 500 rpm. It was really quiet. At the end of the hose, it sounded like an idling rotary engine.
@@irgant Had to translate that using Google but no, i will not pay BMI with my own money to translate it, i'll just watch it on their Russian channel with subtitles or not, either way it's gonna be fine :)
@PaцḶєє BlцєṢтяєєт actually i don't really care about it cause I'm too fat to walk out so I don't have contact with some debil humans who don't know what hygiens are
Wow! Most creative, ideas trying people. I love it. Great work!! Raw and Brutal. Mentioning how the cams the roller rockers Springs everything else will be making noise I'd like to see an update where you dine and insulate the engine bay bottom side and top and try to make the car totally like electric even quieter than the electric motor. YES!
Hey, you should put sound insulation all around the motor, attach a few the super quiet Honda mufflers, and design and make a fully baffled muffler with fiberglass insulation and point the exhaust straight down. (Straight down seems to be quieter.). And I LOVE this channel. Love the things you make and do. It’s all very interesting.
I think the pipes are too wide with this set up they should try half inch pipe from each cylinder, I'm just guessing that's a lot of work just becuase of the amount of custom fabrication to make the pipe fit into each of the mufflers.
For the loud idea: I would suggest Colin Furze's approach. But X4 Furze routed 4 cylinders into one cone-shaped tailpipe over the roof. I'm saying four straight pipes into four huge cones, With as few and as smooth and gradual curves as possible to get to the cones. The cones being about 2 feet across each. Or hell, go all out and do this to the Ladzilla and go for 8 pipes and cones. Regarding the quietest I.C.E. car possible: Adapt a good muffler to the intake, possibly on the snorkel of the air cleaner housing to cut down on the intake sound. Then route all the exhaust pipes into one 2 inch collector, and place several larger mufflers on that, ending with your big dual-tipped muffler you have here. Then attatch a shroud to the radiator fan so that it blows air over the rad, then down under the car, rather than over the engine. Dynamat the engine compartment, everywhere. Under the engine attach chicken-wire and completely fill the engine compartment with very lightly packed fiberglass insulation supported by the chicken wire from falling out below. (Avoiding fouling or jamming the linkages, belts and pulleys, of course) That should quiet the engine sounds. Fit a dynamatted hood and test. The real challenge is to make it look stock from the outside.
Put a glass pack on each group of cylinders (use a good one, mine were 48" long) then connect an H pipe. Then put a big muffler, and optionally a restriction valve and a smaller muffler on the output of each side of the H pipe. Had that on my 67 Fleetwood. When the exhaust manifolds were freshly welded, it was dead silent. The loudest engine noise was from the carburetor.
Now this is a unique idea!! I can't stress enough my worthless opinion on how this creativity is the bomb, but I know a lot of people agree with that! Where else have you seen this idea!?! This was imagination wild as discussion!
For your LOUD exhaust, can you make 2 versions, please? Make one with a high pass filter resonator. Then make another one with a low pass filter resonator.
