Product Details

The Gibson Performance Dual Sport Exhaust System offers a unique side-exit design that combines aggressive styling with practical functionality. Engineered for truck and SUV owners who demand both performance and versatility, this cat-back system exits behind the rear tire—keeping exhaust away from tow trailers while creating a distinctive appearance on or off-road.

Performance Benefits:

  • Dyno-tested to deliver 10-15 horsepower gains and 15-20 lb-ft of increased torque
  • Deep, authoritative exhaust tone with minimal cabin noise
  • Improved exhaust flow for better engine efficiency

Installation & Construction:

  • Bolt-on installation with no welding required
  • Professional-grade components for long-lasting durability
  • Precision-engineered for vehicle-specific fit
  • Backed by Gibson's Lifetime Limited Warranty

This dual sport exhaust system is the ideal solution for drivers who tow regularly and want to avoid exhaust fumes entering the trailer area. The side-exit configuration provides clearance for trailer connections while adding an aggressive, custom look that sets your vehicle apart.
