The Gibson Dual Split cat-back exhaust for 2008–2009 Chevrolet Silverado 1500 LS (4.8L) is an aluminized dual-exit system that reduces backpressure and gives a throaty, aggressive tone. Dyno-tested gains typically average 15–20 hp with improved torque. Polished stainless slash-cut tips exit straight out the back and the baffled Superflow muffler helps minimize interior drone. The system installs bolt-on with included hardware and a lifetime limited warranty.
