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. Product Details:
  • 200cpi high-flow race catalytic converter
  • 3.5" T304 Stainless Steel tubing
  • OE-style Heat shielding
  • 100% TIG-Welded and back purged
  • T304 Stainless Steel 02 bung
  • Great Sound even with factory exhaust, no drone!!
  • Perfect fitment for easy installation
