The CORSA Pro-Series cat-back exhaust is a valveless 3.0in system in 304 stainless steel that replaces the C8's factory valves with straight-through mufflers and included valve simulators, so no valve relearn or check engine light results. It delivers CORSA's Xtreme sound level, the brand's most aggressive note, while patented Reflective Sound Cancellation (RSC) technology holds a drone-free cabin at cruise. The system adds up to 18 hp and 16 lb-ft, weighs about 19 lbs less than stock, and finishes with 4.5in Black PVD dual-wall slash-cut Pro-Series tips.
