Designed to exit behind the rear tire, this system is purpose-built for drivers who demand more from their truck or SUV — whether towing, hauling, climbing grades, or passing on the highway.

Key Features:

  • Maximum Low-End Power: Dyno-tested to produce peak torque and horsepower gains in the critical 1,800–3,000 RPM range — exactly where you need it most for towing and acceleration
  • Proven Performance Gains: Average horsepower increases of 10–15 HP and torque improvements of 15–20 lb-ft over stock exhaust
  • Quieter Cab Experience: Engineered to reduce interior exhaust drone, delivering a performance sound without excessive cabin noise

  • Bolt-On Installation: No welding required — designed for a direct, hassle-free installation with professional-quality results using existing mounting points
  • Premium Construction: Built with high-quality materials and a polished stainless steel tip for long-lasting durability and a finished appearance
  • Lifetime Limited Warranty: Backed by Gibson's Lifetime Limited Warranty for peace of mind
