This was one of the tests I made, just before I found the "secret exhaust trick" that made Formula One cars scream - ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-vA-Z3ncTdUY.html
For real, why did the Keonigsegg jesko absolut act like they were maximizing torque and HP when they put in a flat plane and removed the fucking fly wheel
I have thought that the sound was alot harsher than it should on my old gixxer 750. it turns out it has the titanium manifold from newer K-series 1000 gixxer
Titanium is stronger, so it can be made out of thinner sheet thickness. That's for the biggest part why it sounds different (more vibrations coming trough)
i prefer steel, it sounds smoother and more bassy. The material on the titanium pipe is thinner so it has a lot more vibration, which sounds thinner, more raspy and aggressive
