CTS Turbo 3.0T Downpipe Set
The CTS B8/B8.5 S4/S5 3.0T downpipes are the premier downpipes for your Audi S4 or S5 3.0T. 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 from installing our downpipes.
In addition to being one of the best bang for the buck performance upgrades for S4/S5 3.0T owners our downpipes look stunning. Each pipe is mandrel bent, backpurged and tig welded by hand.
To make installation easier, we made a tool to help remove factory downpipes. Make sure to add it from the drop-down menu.
