The Gibson Dual Split cat-back exhaust for 2001–2005 Chevrolet Silverado 2500 HD (6.0L) offers a stainless, bolt-on replacement that exits straight out the rear with polished tips for a bold sound. Expected dyno gains are around 15–20 hp and increased torque from decreased backpressure. The baffled muffler and mandrel-bent stainless tubing aim to reduce interior drone. Includes factory-style hangers and hardware for a hassle-free install; lifetime limited warranty; no welding required.
