CTS Turbo B8/B8.5 Audi A4/A5/AllRoad/Q5 2.0T Non-resonated Downpipe

The CTS B8/B8.5 A4/A5/AllRoad/Q5 2.0T non-resonated downpipe is another premier exhaust part for your B8/B8.5 Audi A4, A5, Allroad or Q5 2.0T. Our non-resonated downpipe is designed to seamlessly fit in place of your restrictive stock front muffler pipe, 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/Q5 2.0T owners our test pipe is also very attractive piece. Each 3" test pipe is mandrel bent, and hand welded to ensure perfect fitment and longevity. This part is made to replace the factory front muffler, part #2 in the diagram. Product Details:
