i have bullets with 2.5 inch piping, and it has a hint of raspiness during higher rpm shifts. but its hardly noticeable and it actually gives it a nice raw old muscle car sound. with borlas or flows i doubt there woudl be any at all. im willing to bet with 3 inch piping it would probably eliminate any rasp at all with any mufflers. I think rasp is associated with pipe diameter , not limited to just the cats and mufflers...i could be mistaken though...
