Gibson 65400 Cat-Back Dual Sport Exhaust System Stainless Steel

The Gibson Performance Exhaust 65400 Cat-Back Dual Sport Exhaust System is engineered for truck and SUV owners who demand bold style, a deep aggressive exhaust tone, and real, dyno-proven performance gains. Constructed from stainless steel mandrel-bent tubing, this cat-back system maximizes exhaust flow, reduces back pressure, and is built to last for the long haul.

The system exits behind the rear tire, keeping the exhaust path clear of tow hitches and trailers while delivering a distinctive dual-tip look that sets your truck apart on the street or the trail. Installation is completely hassle-free — no welding required. All factory-style hangers and mounting hardware are included for a clean, professional bolt-on fit.
