The Gibson Dual Split cat-back for 2004–2005 Chevrolet Colorado Sport (2.8L) is an aluminized bolt-on system engineered for an aggressive, throaty sound and distinct rear appearance. With stainless dual tips exiting straight out the back, these systems reduce backpressure for typical gains around 15–20 horsepower, work with most bumpers and hitches, and install without welding under a lifetime limited warranty.
