I just bought a 2003 Audi A4 3.0 Quattro. I was wondering if anyone new of any performance upgrades that can be done for this car. I have seen a couple of cat-backs, and 1 intake and that is about it. Anyone know what upgrades are out there and how well they work for my car? If there is a good post I have missed from my searches please let me know. Thanks
