Product Description

The JBA 40-3023 Cat Back Exhaust System is engineered for 2003-2006 Hummer H2 trucks equipped with the 6.0L V8 engine and four-wheel drive. This performance exhaust upgrade replaces the factory system with mandrel-bent 3.00" stainless steel piping and a high-flow muffler for improved exhaust flow, enhanced throttle response, and a deeper, more aggressive exhaust tone.

Designed as a direct bolt-on upgrade, the 40-3023 exhaust uses factory-style hangers and included hardware for an easy installation with no cutting or welding required. The single rear exit and polished stainless tip add a refined touch to your H2's rear profile while delivering noticeable gains in sound and performance over the stock exhaust system.
