Gibson Exhaust 65601 Cat-Back Dual Sport Exhaust System Stainless Steel

The Gibson Performance 65601 Cat-Back Dual Sport Exhaust System is a bolt-on performance upgrade engineered to deliver an aggressive exhaust tone, increased low-end power, and a clean behind-the-tire exit that keeps your setup tow-friendly. Constructed from 409 stainless steel mandrel-bent tubing at 2.25 inches in diameter, this system maximizes exhaust flow while resisting corrosion for lasting durability.

The dual exit routes behind the rear tire — ideal for towing — while giving the vehicle a distinctive street and off-road appearance.
