We are proud to release the new CTS Turbo 3.5″ Stainless Steel High-Flow Cat for the MK7 Golf R/8V Audi S3.  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.


Are you worried about emissions and inspections?  Don’t worry, our optional catalytic converter from Magnaflow should satisfy prying eyes. Precision fabrication, unparalleled quality and great price point all make the CTS Turbo MK7 Golf R/8V Audi S3 High-Flow Cat a must-have for any VW/Audi enthusiast that values performance and their pocketbook.


To remove the CEL that will occur, proper tuning software must be used. CTS Turbo recommends choosing a High Flow Cat for the sake of our environment!


Using the optional CEL eliminator greatly reduces the possibility of CEL coming on for cat efficiency code. This is not 100% effective.


We recommend disabling your Soundaktor (noise amplifier) to fully enjoy the true sound of your motor and remove excessive drone caused by the device.


Using Stage 2 software upgrade is strongly recommended.
