Maybe if you saw and heard it in person? I think you have this impression that the car sounds like a small displacement Honda 4 cylinder with a straight pipe on it...

It doesn't.

Is there rasp? Yes, I can detect the sound of the rasp amid the other exhaust noises, but it definitely doesn't sound like yard equipment.

I mean, I've posted a video in my build thread of revving the damned thing, if all you hear in that sound clip is rasp, then I can't help you. My car is loud and in your face, and if people are laughing at the way it sounds, well, good for them. I'm glad I could give them something to laugh about.

And what's this about power? I'm losing power because I don't have extra pipes hanging off of my exhaust? Do you just make this stuff up as you go along? lmao. Do you even understand what causes the rasp? The mere act of acoustically cancelling out the pulses that generate the rasp can cause back pressure in the exhaust system. You're far more likely to see a power dip at specific RPMs WITH extra resonating chambers attached than you are with a straight pipe as 'canceling out the rasp' is breaking up an acoustic wavefront that helps with scavenging. I assume you know what that is, at least, and why you would not want to do so? This is exactly why you have to be careful with resonance alterations that close to the engine and why I will do no such thing.

THAT is fact, THAT is science. I don't want to make this an acoustics and fluid dynamics debate thread, it's already ridiculous enough.
