OOOOR, you could just dump the F.I. Exhaust and get the Motordyne Shockwave exhaust with ART Pipes, absolutely no rasp with this combo

I hear a lot of talk about the Hiss on decel and revving but barely any talk about acceleration.

I get it with all three. Its annoying when accelerating hard and you get this hissing/rasp along with the VQ sound. Kind of ruins the whole beauty of the VQ exhaust note. I checked under the car and nothing is hitting anything, checked the exhaust and test pipes for leaks or any loose bolts. Everything is fine so i'm guessing its just the nature of these test pipes.

I'm going to try and Wrap the test pipes and see if that helps.

Some people are partial to the VQ hiss. I find it endearing. YMMV.

I think the "hiss" sounds cool... but that's just me. I have Berk test pipes and they are not leaking...still have the hiss when letting off the throttle.
