The Gibson Dual Sport cat-back exhaust for 2007–2012 Chevrolet Avalanche LS (5.3L) is an aluminized system that exits behind the rear tire for a distinctive look while keeping exhaust away from a tow trailer. Dyno-tested to increase horsepower and torque, average gains are 10–15 hp with a 15–20 lb-ft torque boost. Polished stainless tips and a baffled Superflow muffler deliver authoritative tone with minimal cabin noise and bolt-on installation.
