i have a magnaflow, its a universal fit one, i got cutom piping ran from my cat all the way back. its a nice deep growl that doesnt sound ricy at all. i just got tired of the sound because its kinda loud. (and really not that loud..i just got real picky)so i put a larger resonator than the stock one. along with my SRI
its loud enough for me. but magnaflow definitly sounds nice!
