The Gibson Dual Split cat-back exhaust for 1999–2005 Chevrolet Silverado 1500 (4.3L) provides a stainless, bolt-on upgrade that exits straight out the back with polished tips and an aggressive tone. Dyno-tested results typically show 15–20 hp gains and added torque while reducing backpressure. The baffled Superflow muffler, mandrel-bent stainless tubing and minimal interior drone design help preserve cabin comfort. Hassle-free bolt-on installation and lifetime limited warranty.
