I was wondering if anyone can give me advice about getting some nice performance sound out of my 2006 A4 2.0T? I HATE the sound of those done up civic's and likewise, I would love a nice throaty sound similar to that of the 350Z or the G35 but as I drive a 4 banger I'm not sure what I can do? Does anyone know if I could install a blow off valve on the stock turbo? I don't want to mess with the car too much and run into engines problems.
