The Gibson Dual Extreme cat-back exhaust for 2008–2009 Chevrolet Silverado 1500 LS (4.8L) is an aluminized dual-exit system crafted for drivers seeking aggressive sound and bold styling. Mounted behind the rear tires at an angled exit, it delivers dyno-tested gains averaging 15–20 hp. Polished stainless clamp-on tips and a Superflow CFT muffler create a mean tone with reduced cabin drone; the system installs bolt-on and includes a lifetime limited warranty.
