The Gibson Dual Sport cat-back exhaust for 2011–2019 Chevrolet Silverado 2500 HD LT (6.0L) is an aluminized system that exits behind the rear tire for a distinctive look and to avoid affecting a tow trailer. Dyno-tested to boost power, typical increases are 10–15 hp with 15–20 lb-ft of torque. Polished stainless round slash-cut tips and a baffled Superflow muffler minimize interior drone; installation is bolt-on and the system carries a lifetime limited warranty.
