Product Details

The Gibson 5670 Dual Sport Cat-Back Exhaust System is a bolt-on performance upgrade built for truck and SUV owners who want aggressive sound, real power gains, and a clean look that exits behind the rear tire — keeping the path completely clear for towing. Constructed from heavy-duty aluminized steel mandrel-bent tubing, this system maximizes exhaust flow and is backed by Gibson's Lifetime Limited Warranty.

Dyno-Proven Performance:

Engineered to deliver peak power gains in the critical low-end RPM range (1,800–3,000 RPM), this system produces an average increase of 10–15 horsepower and 15–20 lb-ft of torque — performance that's dyno-tested and verified before leaving the factory.

Key Features:

  • Dual exit design routes exhaust behind the rear tire for a clean, aggressive appearance with no interference with trailer hitches or tow equipment
  • Baffled and chambered Superflow muffler — no internal packing — delivers an aggressive exhaust note with minimal interior drone
  • 2.25" aluminized mandrel-bent tubing for maximum exhaust flow and long-term durability
  • Polished T-304 stainless steel slash-cut rolled tips — 2.25" inlet, 4.0" outlet, 12" length — clamp-on design for a clean, professional finish
  • Muffler specs: 8" round body, 3" offset inlet, 2.25" dual outlet, 24" body length
  • Bolt-on installation using factory mounting points — no welding required
  • Backed by Gibson's Lifetime Limited Warranty

The Gibson Dual Sport series delivers a powerful, authoritative exhaust tone without annoying cabin drone, making it an ideal upgrade for daily drivers, weekend warriors, and trucks that see double duty on the street and trail.
