The CORSA Xtreme valved cat-back exhaust for the CT4-V Blackwing uses 3.0 in 304 stainless steel tubing and a 3.0 in double X-pipe that replaces the crushed factory piping near the rear axle, for a 10% flow increase over stock. It plugs directly into the factory dual-mode Active Exhaust module, so the drive mode selector moves the sound between Xtreme and Sport, and CORSA rates it about 7 dB louder than stock. RSC No Drone technology tuned for the 3.6L twin-turbo LF4 V6 keeps cruise drone free in any valve position. The dual rear exit system finishes in dual-wall 4.5 in Black PVD Pro-Series slash-cut tips and is made in the USA.
