We are proud to release the new CTS Turbo 3.5" High-Flow CAT for Mercedes-Benz M133 A45 AMG, CLA 45 AMG and GLA 45 AMG.
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 tuned. The CTS Turbo 3.5" high-flow catalytic converter downpipe will allow for your exhaust gases to flow smoothly, freeing up the additional ponies that you want, all while look amazing.
