Product Description

The Corsa 14789 Xtreme Axle-Back Exhaust System is purpose-engineered for 2016-2024 Camaro SS and 2017-2024 Camaro ZL1 models equipped with the GM factory dual-mode NPP performance exhaust. This upgrade replaces the OEM axle-back section with mandrel-bent 2.75- stainless tubing and straight-through mufflers to deliver maximum flow and aggressive tone without cabin drone, thanks to patented RSC® technology and variable NPP valve control.

Featuring quad 4.0- polished Pro-Series tips in a dual rear exit layout, the 14789 integrates seamlessly with the stock NPP actuator and reuses the factory module - no special adapters required. The system offers about 18% better flow over stock and maintains clean sound tuning with over 12-dB tone shift when valves open or close. Installation is bolt-on and clamp-fastened; no cutting needed.

Designed and built in the USA with T-304 stainless steel and backed by CORSA's limited lifetime warranty (and a 5-year valve warranty), the 14789 offers Camaro owners drone-free comfort, enhanced performance, and striking styling in one high-performance package.
