The Gibson single-side cat-back exhaust for 2002–2005 Chevrolet Silverado 1500 (4.3L) is tuned for improved acceleration and hill-climbing power with a rear exit to minimize in-cab noise. Aluminized mandrel-bent tubing and a baffled Superflow™ muffler optimize flow for low-end torque and typical 10–15 horsepower gains. It installs bolt-on using included hardware and factory-style hangers.
