Candyman, good choice I am using the same set up, its great! Now put your stock T header on your Rs4 3.
Christian, you WERE the first person I had heard about that header from. And I like other people said "Duratrash" I don't think so, but now after running stock, CEN, NJBT gen1, and now the duratrax, and all four with the AE pipe, I definately think the Duratrax Ae combo is great! Not to mention its only $11 with the gasket, screws, and a silicone coupler too.
