I was afraid it was going to sound high pitched and ricey, but the only time it really gets loud is 5000+ RPM and I only hit that on the highway. As for performance, as long as you have a perforated core type muffler (meaning, without the baffles) you're going to get about the same improvements in exhaust flow on any given brand of exhaust (assuming they are all the same diameter). Basically all you're doing is reducing the psi in backpressure. Stock pipes usually generate about 12-15 psi whereas an aftermarket system can reduce it to about 6-8 psi. Just to give you a better idea, rally cars using test pipes (straight back, no cat or muffler) generate about 1 psi.
