Product Details

The Gibson 65403 Dual Extreme Cat-Back Exhaust System delivers a bold combination of aggressive sound, standout styling, and dyno-proven performance gains. Constructed from T304 polished stainless steel with 2.5-inch mandrel-bent tubing, this dual cat-back system is engineered for maximum flow and long-lasting durability. Exhaust exits behind each rear tire at an aggressive angle for a distinctive street presence.

Every component is dyno-tuned and application-tested to reduce backpressure and maximize power output. Dyno-tested results show gains of up to 15 horsepower and 30 lb-ft of torque, with peak performance targeted in the low-end RPM range where trucks and SUVs need it most.
