bleh no DIY exhaust for my car on that website. O well I'll keep looking.

One more question though. I just put my new Carbonio Intake system in my car and it sounds like a blow of valve ever time i left off the gas pedal. Im new to turbo'ed cars and im just wondering if thats normal for the intake to sound like that?

 

It's normal since the air flow is better. Not sure about the blow off valve sound if your car got the stock DV but from my experience, when I installed my hybrid dv/bov, at first, I couldn't hear it much, but after I install my carbonio intake, I could hear a loud psssshhh noise even at very low boost.

 

alright thanks man

 

I believe A4 Mods has a diy for installing an aftermarket exhaust.
