Product Details

The Gibson 6545 Dual Sport Cat-Back Exhaust System is engineered for truck and SUV owners who want a bold exhaust note and clean exterior appearance without interfering with towing operations. The dual exit design routes exhaust behind the rear tires, keeping the path clear for tow hitches and trailers while giving your vehicle a purposeful, aggressive stance on the street or the trail.

This is a complete bolt-on system — no welding required — delivering professional-quality results with a straightforward installation process. Every Gibson 6545 system is dyno-tested and proven to deliver average gains of 10–15 horsepower and 15–20 lb-ft of torque. The system is backed by Gibson's Lifetime Limited Warranty.

  • Design: Baffled and chambered — no internal packing material
  • Sound profile: Aggressive, authoritative deep tone with minimal interior cab drone
  • Shape: 7 in. round body
