Product Description

The Gibson 5572 Dual Extreme Cat-Back Exhaust System is a performance-oriented bolt-on upgrade specifically designed for 2007-2014 Chevrolet Avalanche 1500, Chevrolet Suburban 1500, and GMC Yukon XL 1500 models equipped with the 5.3L V8 engine. This extreme-tone exhaust replaces the factory setup from the catalytic converter back using mandrel-bent aluminized steel tubing and a Superflow™ baffled muffler to increase exhaust flow for improved low-end torque and horsepower while delivering a deeper, more aggressive exhaust note with reduced cabin drone. The polished stainless steel slash-cut tips and split side exit design add premium visual appeal behind each rear tire.

Installation is straightforward with included factory-style hangers and all required hardware - no welding is required, making this a true bolt-on system. Designed to work with stock exhaust hangers and clearances, the 5572 exhaust enhances throttle response, towing capability, and overall driving experience. Backed by Gibson's lifetime limited warranty, fitment is confirmed for the listed 2007-2014 5.3L V8 truck and SUV models; coverage beyond these years is unconfirmed at time of listing.
