Right now I have the DC header, invidia s-pipe, custom mid and greddy evo 2 axelback. I am trying to find what resonator/high flo cat combo to put on to get a super smooth sound. I mean ZERO rasp throughout the whole rpm range. As of right now my two resonators muffled my exhaust a bit too much.

can those of you with a full header/ straight pipe setup that HAVE that super smooth sound tell me what you used please? thanks guys.

 

vibrant hi-flow cat. took the rasp away completely, just the exhaust is louder than before the header

 

sweet what size?

 

2.25". the skunk2 piping is 2.5 (2.36) so i chose the smaller one for more resonance.
