CTS Turbo 3.5" Downpipe High-Flow CAT for Mercedes-Benz M133 A45/CLA45/GLA45 AMG

Wake up your Mercedes-AMG M133 with the CTS Turbo 3.5" high-flow catted downpipe, a direct cure for the choked factory downpipe that throttles power once you start tuning. Opening up the path off the turbo lets exhaust gases scavenge freely, releasing the horsepower the OE pipe holds back — and it looks the part too.
