Product Information
The CORSA Xtreme cat-back exhaust for the CT5-V runs 3.0 in 304 stainless steel tubing through a 3.0 in double X-pipe that eliminates the crushed factory piping near the rear axle, for about 10% more flow than stock. It plugs directly into the factory dual-mode Active Exhaust module, so the selected drive mode quiets or opens the system, and CORSA rates it over 5 dB louder than stock. RSC No Drone technology tuned for the 3.0L turbo V6 keeps the cabin drone free at cruise regardless of valve position. The dual rear exit system finishes in dual-wall 4.5 in carbon fiber tips with Black PVD finish and is made in the USA.
