Amazing Crackles and pops, enhances performance and sound CTS Turbo downpipe 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 downpipe will allow for your exhaust gases to flow smoothly, freeing up the additional ponies that you want, all while look amazing. Highlights of cts downpipe include CNC machined turbine discharge (downpipe), 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
