I have a stock 2000 A6 2.7T and I need a new exhaust for it. My mechanic told me that it has a leak in it so I need a new cat back exhaust. I don't even know where to begin looking for an exhaust. I want the exhaust to sound good and deep but relatively quiet while still getting as much power from the exhaust as I can. Does anyone have any suggestions about what exhaust I should put on my stock a6 that will give me some power while still keeping it relatively quiet?

 

If you have a tiptronic then it's going to be harder to find an exhaust.

Check out APR and milltek. It will probably also be the same of not cheaper than the exhaust at the dealer
