Gibson 9008 Cat-Back Dual Extreme Exhaust System Aluminized 2.5in Dual Exit

The Gibson 9008 Cat-Back Dual Extreme Exhaust System is a bolt-on performance exhaust upgrade engineered for truck enthusiasts seeking aggressive sound, bold dual-exit styling, and real dyno-proven power gains. The system exits behind each rear tire at an aggressive angle, delivering a commanding exhaust tone without sacrificing drivability.

Constructed from aluminized heavy-duty steel tubing, the system uses mandrel-bent 2.5-inch tubing throughout to maintain a constant pipe diameter through every bend — maximizing exhaust flow, reducing backpressure, and improving throttle response. Dyno-tested for the specific application, this system delivers average gains of 15–20 horsepower. No cutting or welding is required for installation — the system is a direct bolt-on replacement for the factory cat-back exhaust.
