CTS Turbo Audi 3.0T Supercharged V6 Downpipe Set

The CTS CTS Turbo Audi 3.0T Supercharged V6 Downpipe Set is the premier downpipes for your Audi 3.0T V6 equipped with a supercharger.  Our downpipes are designed to seamlessly fit in place of your restrictive stock downpipes, which are situated immediately after your catalytic converters.  Our Downpipes feature 2.5" stainless steel piping, smooth mandrel bends, and stainless steel flex sections. Substantial power gains, improved exhaust flow and a more throaty sound are the main benefits of installing our downpipes. In addition to being one of the best bang for the buck performance upgrades for S4/S5/Q5/SQ5/A6/A7 3.0T owners, our downpipes look stunning. Each pipe is mandrel-bent, back purged and tig welded by hand. To make installation easier, we made a tool to help remove factory downpipes. CTS-HW-0273 Product Details:
