Dominating Performance & Style

The Gibson Dual Sport Series is a true testament to our commitment to high performance and striking aesthetics. Engineered for peak low-end torque and horsepower (1,800–3,000 RPM), the Gibson Dual Sport Series delivers dyno-proven gains of 10–15 horsepower and 15–20 lb-ft of torque—performance you can feel.

Aggressive Sound, Minimal Drone

Equipped with a Superflow Muffler featuring a baffled and chambered design—without internal packing—this system minimizes drone while producing an aggressive exhaust note. It maximizes power while keeping cabin noise lower than other performance exhausts.

Built to Perform, Designed to Last

Crafted from quality heavy duty aluminized steel mandrel-bent tubing, this exhaust system ensures maximum flow and durability. Each precision-engineered T-304 stainless steel tip delivers a bold, aggressive look that stands out. Featuring a clamp-on design for easy installation, it’s the perfect blend of style and function.

Installation is made easy with all necessary factory hangers and clamps included, ensuring a seamless, bolt-on setup—no welding required, just professional results.

Proudly Made in the USA, the Gibson Dual Sport Series comes with a Lifetime Limited Warranty, ensuring years of high-performance driving.
