Gibson 315547 Single Side 4in Cat-Back Exhaust for Select 2001-2006 Chevrolet/GMC 2500 HD/3500 (6.0L) - Aluminized

Fits select 2001-2006 Chevrolet Silverado and GMC Sierra 2500 HD and 3500 models (6.0L).

Gibson Single Side Exhaust systems are engineered to improve your truck's utility and driving experience by maximizing low-end torque and horsepower between 1,800 and 3,000 RPM. This specific power band focus makes it an ideal upgrade for heavy-duty 2500 and 3500 series trucks used for towing, hauling, and hill climbing. The system features large-diameter 4-inch mandrel-bent aluminized tubing to maintain consistent exhaust flow and reduce backpressure.

At the heart of the system is the Superflow™ baffled and chambered muffler. Unlike traditional performance mufflers that use internal packing that can blowout or degrade over time, this chambered design remains consistent and provides an aggressive exterior note with minimal interior drone. Installation is straightforward and utilizes factory-style hangers and included hardware for a true bolt-on fitment without the need for welding.
