The Gibson Dual Split cat-back exhaust for 2010–2013 Chevrolet Silverado 1500 LS (4.8L) is an aluminized dual-exit system that reduces backpressure and produces a throaty, aggressive sound. Dyno-tested gains typically fall in the 15–20 hp range with added torque. Polished stainless slash-cut tips exit straight out the back and a baffled Superflow muffler helps limit interior drone. Installation is hassle-free bolt-on and the system is backed by a lifetime limited warranty.
