The Gibson Super Truck cat-back exhaust for 2008–2009 Chevrolet Silverado 1500 LS (4.8L) is an aluminized system tuned for a loud, deep race rumble with dual tailpipes exiting in front of the rear tires. Dyno-tested gains typically run 10–15 hp with 15–20 lb-ft torque increases. This aggressive system is bolt-on but not recommended for towing; noise may exceed the 95-decibel standard. Installation is hassle-free and the system carries a lifetime limited warranty.
