Gibson Dual Extreme 2.25in Cat-Back Exhaust for 2007-2014 Chevrolet Avalanche, Suburban & GMC Yukon XL (5.3L) - 5572

Fits 2007-2014 Chevrolet Avalanche, Suburban 1500, and GMC Yukon XL 1500 (5.3L).

The Gibson Dual Extreme Cat-Back Exhaust system is engineered for drivers seeking an aggressive, performance-oriented tone with a distinctive look. This system features dual tailpipes that exit at an angle behind the rear tires, providing a bold aesthetic and high-clearance functionality. At the heart of the system is the Superflow CFT muffler, a baffled and chambered design with no internal packing to blow out, ensuring a consistent, powerful sound with minimal interior drone.

Constructed from aluminized mandrel-bent tubing, this kit is designed to optimize exhaust flow. The 2.25-inch diameter piping helps produce average gains of 15-20 horsepower while maintaining the backpressure needed for low-end torque. The system is finished with polished stainless steel slash-cut tips for a premium look. Installation is a straightforward bolt-on process using factory-style hangers, requiring no welding or specialized fabrication.
