i got a question of my own. with so many questions regarding exhaust systems, i was wondering about headers and manifold for audi. is there a co. that makes universal aftermarket parts for audi, i looked and can only find maybe stuff for 1.8T and that's about it. i'm thinking of def. getting an audi in the future, and no such luck. sure there's exhaust kits, ECU upgrades, performance clutch, suspension kits, and even a short shifter, but aside from that nothing on after market engine parts. i asked in the past and redgoat was looking into cam kits too, but to my research, no luck there either. so if anyone's got info, help would be much appreciated... next question for me ya'll prob ask is what type of audi will i be getting? well, for now it doesnt matter. just a universal store that specializes in AUDI.
