The Gibson Dual Sport cat-back exhaust for 1999–2001 Chevrolet Silverado 1500 (4.3L) exits behind the rear tire for a distinctive look that preserves tow-trailer compatibility. Dyno-tested to add horsepower and torque (typically 10–15 hp and 15–20 lb-ft), it uses mandrel-bent stainless tubing, a baffled muffler for a deep tone with minimal cabin drone, and polished clamp-on tips. Installation is bolt-on and requires no welding.
