CTS Turbo are proud to release their 3.0' Stainless Steel downpipe for the MK1 TT225Q.  Unfortunately, the factory downpipe that comes as standard equipment in your car was designed for anything but performance.  The factory downpipe severely restricts exhaust flow and therefor has adverse effects on horsepower, especially once your car is “chipped”.  The CTS Turbo downpipe will allow for your exhaust gases to flow smoothly, freeing up the additional ponies that you want, all while look amazing.  Highlights of their downpipe include CNC machined turbine discharge (downpipe) flange, mandrel bent 3' stainless steel tubing, modular design making installation of a catalytic converter simple and straight forward, smooth transitions allowing for optimal exhaust gas flow.

Are you worried about emissions and inspections?  Don’t worry, our optional high flow catalytic converter should satisfy prying eyes.  Precision fabrication, unparalleled quality and and great price point all make the CTS Turbo MK1 225Q Downpipe a must have for any Audi enthusiast that values performance and their pocketbook.
