Gibson Exhaust 65514 Cat-Back Super Truck Exhaust System Stainless Dual

The Gibson Performance Exhaust 65514 is a cat-back Super Truck exhaust system engineered to deliver an aggressive race truck rumble with real, dyno-proven performance gains. Featuring dual tailpipes that exit in front of the rear tires, this stainless system combines maximum flow with a bold sound profile that stands out from the factory exhaust.

At the core of the system is Gibson's patented Superflow™ muffler — a baffled and chambered design with no internal packing — which minimizes interior drone while producing an unmistakably deep and aggressive tone. Noise level may exceed 95 decibels. Tubing is constructed from 409 stainless steel and mandrel-bent to 2.50-inch diameter, ensuring consistent exhaust flow with minimal backpressure. Slip-fit connections further reduce backpressure at pipe joints.

Each system ships with a 6-inch polished T304 stainless, oblong slash-cut clamp-on tip (outlet: 6 x 2.75 in.) for a clean, finished appearance. Dyno testing demonstrates average gains of 10–15 horsepower and 15–20 lb-ft of torque.
