Nissan 370Z Forum - View Single Post - Hissing noise from 370z aftermarket exhaust system

I went from stock to BERK HFC with stock exhaust, then added the Berk Exhaust (X-pipe) and now I'm back to stock cats and Berk exhaust. In my experience:

HFC = Hiss
HFC + x-pipe CBE = More hiss
Stock cats + X-pipe CBE = no (to me noticeable) hiss

All in all I like my current set up the best, nice added volume, no drone, no hiss.
