The Gibson single-side cat-back exhaust for 1999–2001 Chevrolet Silverado 1500 LS (4.3L) delivers improved low-end torque and acceleration for towing and passing. Dyno testing indicates typical gains of 10–15 hp and 15–20 lb‑ft between 1800–3000 rpm. Built in stainless with mandrel bends, a baffled Superflow muffler and polished slash-cut tip, it includes hardware and factory-style hangers for a bolt-on, no-weld install, reduced in-cab drone and a lifetime limited warranty.
