does the Z have an air injection system that shoots clean air into the exhaust to try and clean up the emissions? this could very easily be the cause of the hiss, if our cars have them. thats what it sounds like. uz the car even hisses in stock form...

I noticed the ERZ HFCs don't cause much hiss... Anyone know about the Invidia HFCs?

I don't have much experience with their CAT replacement options but I do know I like their CBE systems.

The exhaust system vibrates pretty violent on decel especially with HFC's. We take the factory 370 weights & add 2 more to the system which makes them alot less hissy

Put one on the lift & rev the motor & watch the show

I have the ARK exhaust with Stock cats and I have no hiss whatsoever.

Damb it, I have the hiss! I just put on the Berk TP, that noise it horrible! I think I am going to put the stock cats back on and wait till I get the Stillen CBE then put them back on and see. And I got a CEL, I havent found anything for electronically fixing but I think I will go down to the local racing shop and pick up some 90deg bung inserts, see if that fixes it. Freakin Hiss!
