Product Details

The Gibson Performance Exhaust 5663 Dual Sport Exhaust System is a cat-back exhaust designed for truck and SUV owners who want an aggressive exhaust note without compromising towing capability. The dual exit configuration routes exhaust behind the rear tires, keeping the tailpipe clear of trailer hitches and tow setups — a practical advantage for those who haul regularly.

Gibson engineered this system to deliver a deep, authoritative exhaust tone that remains cabin-friendly, eliminating the interior drone common with aftermarket exhausts. Each system is dyno-tested to verify real-world performance gains, with average increases of 18–20 horsepower and 15–20 lb-ft of torque.

Key Features:

  • Dual cat-back design exits behind the rear tires — tow-hitch friendly
  • Deep, aggressive exhaust tone with minimal interior cabin noise
  • Dyno-tested for verified horsepower and torque gains
  • Average gains of 18–20 HP and 15–20 lb-ft of torque
  • Bolt-on installation — no welding required
  • Mandrel-bent tubing for maximum exhaust flow
  • Stainless steel construction for long-term durability and corrosion resistance
  • Backed by Gibson's Lifetime Limited Warranty

Installation is straightforward and designed for a professional-quality finish without professional-level tools. The Gibson 5663 Dual Sport system is an ideal upgrade for truck and SUV owners seeking improved performance, a distinctive exhaust note, and tow-ready exhaust routing.
