CORSA Xtreme Axle-Back Exhaust for 2016-2024 Chevrolet Camaro SS/ZL1 6.2L V8
Part number 14789 is the CORSA Xtreme Axle-Back Exhaust engineered for the 2016-2024 Chevrolet Camaro SS/ZL1 6.2L V8. It features twin 4.0in polished tips.
The CORSA Performance Xtreme Axle-Back Exhaust is designed for Chevrolet Camaro SS and ZL1 models equipped with the 6.2L V8 engine and factory dual-mode NPP valves. CORSA Reflective Sound Cancellation (RSC) Technology creates an aggressive exhaust note under acceleration while maintaining a drone-free experience during cruising.
This valved exhaust system uses Dual-Mode NPP functionality to let drivers customize the sound of the vehicle. Sound selection does not affect the system's stated performance gains. The system features a dual rear exit with twin 4.0in Pro Series tips and retains the GM factory axle pipes with AFM valves. Installation requires the factory GM NPP Valve Module.
Designed for bolt-on installation, the system plugs directly into the factory dual-mode NPP module. Its 304 stainless steel construction, polished dual-walled tips, and robust valve assembly are designed for long-term use. The system flows 18% better than stock and is made in the U.S.A.
