CTS Turbo - 3" Downpipe and High-Flow Cat - TT Mk1 FWD

We are proud to release the new CTS Turbo 3″ Stainless Steel High-Flow Cat for the 1.8T.  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 High-Flow Cat will allow for your exhaust gases to flow smoothly, freeing up the additional ponies that you want, all while look amazing.  Highlights of our High-Flow Cat 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.

Precision fabrication, unparalleled quality and great price point all make the CTS Turbo 1.8T High-Flow Cat a must-have for any VW enthusiast that values performance and their pocketbook.

To remove the CEL that will occur, proper tuning software must be used.
