Thanks again, and btw your car looks f'n sweet.

 

Anytime buddy and thanks

 

this is my car, i tinted it myself

 

Hey man I have the same car, I love the sound of the turbo also but anyways all you need to get is a blowout valve. You can talk to a couple tech people or just search on google 2002 AUDI A4 blow out valve. If I were you dont go cheap but put in a good brand one that you can trust. Also it adds a couple horsepower. Did you get quattro? If you did dont bag off start to hear turbo and heat up your car in the morning if you live in a cold area.
