Gibson 65672 Cat-Back Dual Sport Exhaust System Stainless Steel

The Gibson 65672 Cat-Back Dual Sport Exhaust System is engineered for truck and SUV owners who want a clean, tow-friendly exhaust setup with real performance gains. The dual-exit design routes exhaust tips behind each rear tire, keeping the system completely clear of tow hitches and trailers while delivering a bold, aggressive look on or off the road.

Powered by Gibson's proven Superflow muffler technology, this system uses a baffled and chambered design with no internal packing material, producing a deep, authoritative exhaust tone with minimal interior drone. Dyno-tested tuning delivers average gains of 18–20 horsepower and 15–20 lb-ft of torque, optimized for peak low-end power in the 1,800–3,000 RPM range where trucks spend most of their time.

Construction features 409 stainless steel mandrel-bent tubing (3.5 in. primary / 2.25 in. secondary) for unrestricted exhaust flow and long-lasting durability. The system is finished with clamp-on 4 in. polished T304 stainless rolled slash-cut tips for an aggressive, show-quality appearance.
