The Gibson single cat-back exhaust for 1996–1999 Chevrolet Astro LS (4.3L) is a stainless single-side system that exits behind the rear tire and improves low-end torque and towing performance. Its baffled Superflow muffler and mandrel-bent tubing provide typical 10–15 horsepower gains with subdued in-cab sound. The kit includes all hardware and factory-style hangers for hassle-free bolt-on installation and is protected by a Lifetime Limited Warranty.
