The Gibson Dual Split cat-back exhaust for 1999–2005 Chevrolet Silverado 1500 (4.3L) is a stainless bolt-on system that exits straight out the rear with polished tips and a throaty tone. Engineered to decrease backpressure, it produces typical gains of 15–20 hp and improved torque. The baffled muffler minimizes interior drone while stainless mandrel-bent tubing and included hangers simplify installation. No welding needed; backed by a lifetime limited warranty.
