Gibson 66548 Cat-Back Dual Sport Exhaust System Stainless Steel

The Gibson 66548 Dual Sport Cat-Back Exhaust System is a bolt-on performance upgrade engineered to deliver a deep, aggressive exhaust tone alongside measurable power gains — all without increasing cabin noise. Dual tips exit cleanly behind the rear tire, keeping the exhaust path clear of tow trailers and giving your truck or SUV a purposeful, distinctive stance on the street or trail.
