I just bought a 06 A4 2.0T. Ive had other cars and did mods but they were all v8s and im new the V4 turbo...i found a post on yahoo answers about mods. I would like to upgrade my exhaust but i do not want the ricer sound and all that raspy stuff. i would like clean quiet exhaust. What would you suggest. I also wanna invest in a AEM cold air intake and GICA chip along with a diode mod for the turbo. would this be a good setup? please im open for anything what do you think?
