after my new down pipe and the new 10:1 pistons my exhaust is ear defening loud and ricey. i hate it now. i have the pacesetter header, custom made catless 3 inch down pipe, to a full 3 inch custom made "catback" to a 3 inch magnaflow race series muffler, i like the tone of it, just not how loud it is, it wasnt nearly this loud before the piston swap, and down pipe and header. is there a good resonator i can use?

 

The best thing you could do for the tone of your exhaust would be to put a cat back on. But if you really want to stay cat-less, I'll defer to the other members to suggest a resonator because I'm really not sure.

 

Your going to want to put in two 3inch resonators, one where the cat use to be, and another before the d/p.
