The Gibson Dual Split cat-back exhaust for 2002–2005 Chevrolet Silverado 2500 HD (6.0L) is an aluminized dual-exit system that reduces backpressure and gives an aggressive throaty sound. Dyno-tested gains typically average 15–20 hp while torque improves. Polished stainless tips exit straight out the back; the baffled Superflow muffler minimizes interior drone and the system installs bolt-on with a lifetime limited warranty.
