CORSA Performance C8 NPP Cat-Back Exhaust

The CORSA Performance NPP Only C8 exhaust is a 3.0-inch cat-back dual rear exit system designed for Chevrolet Corvette models equipped with the GM factory optional performance exhaust. It features fully functional CORSA Cast NPP valves that integrate with the stock C8 actuators, helping maintain factory sound-level functionality while providing more aggressive exhaust notes under acceleration.

This system uses CORSA's proprietary RSC® technology for a drone-free driving experience and includes an AFM machine valve simulator engineered to help prevent an AFM check engine light. The exhaust features 304 stainless steel construction, CORSA Performance mufflers, and 4.5-inch Black PVD Pro-Series tips. CORSA recommends professional installation.

Dyno-tested results show gains of up to 19 horsepower and 16 lb.-ft. of torque over the optional factory performance exhaust. The system is designed for drivers who primarily use V8 or Track mode and want to switch between Sport and Xtreme sound levels while maintaining all sound modes.
