Product Description

The CORSA Performance 21789CF is a Dual-Mode Active Valve NPP axle-back exhaust system for the 2016-2024 Chevrolet Camaro SS (4-tip NPP) and 2017-2024 Camaro ZL1. It integrates directly with the factory NPP valve actuators and reuses the OEM NPP module, allowing drivers to maintain full access to Tour, Sport, and Track exhaust modes without any additional electronics or control hardware.

The system combines CORSA's patented RSC® (Reflective Sound Cancellation) technology with the factory NPP variable valve system, delivering over 12 dB of sound level difference between open and closed valve positions - all while keeping the cabin completely drone-free at cruise in any mode. Carbon fiber quad 4.5" tips with polished stainless Pro-Series inner cones provide an aggressive, high-end appearance. Important: this system does not fit Camaro models equipped with the OEM Ground Effects Package (GM P/N 84132660 or 84132661).
