Mostly when searching for exhausts on this site, you get 50% good and 50% bad for Milltek, however, I've always been impressed with Supersprint, ever since I first heard one on a Golf VR6.... I know they make cat back systems for Audi A3 1.8T, but do they make high flow cats and where would I go to get one supplied and fitted? Manufacturers like Blueflame and Hayward and Scott can supply but they have to be custom made, which adds to the price and the possibility of it not being 100%. So, any suggestions? Anywhere doing Supersprint for Audi's?
