Built for drivers who demand performance, sound, and style, the Gibson Super Truck Exhaust System transforms any vehicle into a head-turning performer. Dual tailpipes exit before the rear tires, finished with polished 6-inch T-304 stainless steel slash-cut tips for durability and visual impact.

At its core, the Gibson Superflow muffler features a baffled and chambered design with no internal packing. This provides a deep, aggressive exterior tone while minimizing cabin drone. Performance is optimized in the low-end RPM range (1800–3000), offering noticeable gains in acceleration, torque, and pulling power—exactly where it matters for daily driving or towing.

Constructed from mandrel-bent 2.50-inch 409 stainless steel tubing, the system is engineered for maximum durability and smooth exhaust flow. All necessary clamps and factory-style hangers are included for a 100% bolt-on installation—no welding required.
