The Gibson Dual Extreme cat-back exhaust for 1999–2001 Chevrolet Silverado 1500 (4.3L) is a stainless bolt-on system that exits behind the rear tires at an aggressive angle to deliver a mean, powerful tone and bold street presence. Dyno-tested to yield typical gains of 15–20 horsepower, it uses a baffled chambered muffler, mandrel-bent tubing and polished slash-cut tips. Installation is bolt-on with included hardware, no welding, and it carries a lifetime limited warranty.
