I have talked to the people from Corsa(Jeff) about my problem with a loud hissing noise coming from my exhaust. They claim that if you have an aftermarket exhaust and an aftermarket cold air intake than you will hear a loud hissing noise whenever the gasis pressed. This question is for the people who own both and intake and exhaust, do you get the same hissing noise, almost like a turbo whine?

[QUOTE=hcvone]No "hissing" noise here with my exhaust and air intake, I seem to remember "hissing" noises from my K&N FIPK but that was some years ago.

I get a loud hiss from the exhaust whenever the gas is pressed down. They explained that it is the intake going through the freeflow exhaust. I just want my cadillac to be back to normal. I am thinkign of selling my vararam intake on ebay, any buyers?
