The Gibson Super Truck cat-back exhaust for 2010–2013 Chevrolet Silverado 1500 LS (4.8L) is an aluminized system that produces a loud, deep race rumble with dual tailpipes exiting ahead of the rear tires. Expect dyno-tested gains of about 10–15 hp and 15–20 lb-ft of torque. This bolt-on system delivers aggressive sound but is not recommended for towing; noise may exceed the 95-decibel standard. Includes hardware and a lifetime limited warranty.
