i am ordering a obx twin loop muffler(mugen knockoff) for 75$ i have a 300$ price rang for piping muffler cat and resonator. which cat and resonator should i go for and what size piping? i want the really deep sound without being raspy at all

-90 integra sedan

 

For your cat, dont get a test pipe, really loud and raspy. If it is an integra(which you have not stated) then go with 2.5in piping.

 

yes its an integra, and what cat and resanator?

 

I have always heard good things about Vibrant resonators. And a magnaflow hi-flow cat will do the trick.
