The CTS B8/B8.5 A4/A5/AllRoad 2.0T non-resonated downpipe is the premier downpipe for your Audi A4 or A5 or Allroad 2.0T.

Our non-resonated downpipe is designed to seamlessly fit in place of your restrictive stock resonator/downpipe, which is situated immediately after your Catalytic converter/Test Pipe/HFC. Our Downpipe features 3″ stainless steel piping, smooth mandrel bends, and a stainless core-interlock steel flex section. Improved exhaust flow and a more throaty sound are the main benefits from installing our downpipe. In addition to being one of the best bang-for-the-buck exhaust sound upgrades for A4/A5/AllRoad owners our test pipe is also very attractive piece. Each 3″ test pipe is mandrel bent, and hand tig welded.
