Exhaust Hiss - Honest Thought ?!

I didn't have any hiss with the Berk Cat Backs until I installed their High Flow Cats...Personally, I don't think this setup sounds too bad even with the slight hiss.

Well..I don't know about that since I also have the F.I, but then again i have the NR CF version..And I get the hiss..It might not happen with NR Stainless Steel version?

I have a awful hiss when I let go of the throttle. it sounds like there is a leak or my muffler has something rattling around in it. Didn't have the hiss even after I installed the Z1 Test pipes and Headers. I'm running a Borla Catback. Should I get a new catback and see if that changes anything. Thinking of getting Greddy Evo Gt.
