The best catback exhaust

Hey guys,

I would like to know what catback exhaust everyone is using. I'm looking for one that will create good mid to high rpm power, while maintaining a pleasant and deep sound. If you have a catback exhaust that you are satisfied with and would like to recommend, please feel free. Also, will free flowing exhausts keep me from passing smog even though I have my catalytic converter and all other necessary equipment? If so, then a C.A.R.B. approved exhaust would be a major plus, but if not thats okay.

i like my thermal r&d cat back. good sound, and not too loud. the exhaust doesnt matter for smog, you just need somethign there. and an aftermarket exhuast will not affect your smog test.

Thats what I was thinking. Cool. I've some good things about Thermal R&D. I might try it out.

I like my Thermal, it's a good sounding cat back, not ricey at all

greddy systems have always sounded good to me also
