Product Details

The Gibson Exhaust 66604 Cat-Back Dual Sport Exhaust System delivers aggressive styling and enhanced performance for trucks and SUVs. This unique dual-exit system routes exhaust behind the rear tire, providing a distinctive appearance while keeping exhaust away from tow trailers—perfect for both street and off-road use.

Performance Benefits:

  • Dyno-tested gains of 10-15 horsepower and 15-20 lb-ft of torque
  • Deep, authoritative exhaust tone with minimal interior drone
  • Baffled and chambered muffler design with no internal packing
  • Complete bolt-on installation—no welding required

Construction & Components:

  • Stainless steel construction for durability and corrosion resistance
  • Round muffler: 8-inch diameter, 24 inches long with 2.50-inch dual inlet/outlet
  • Premium 4-inch polished T304 stainless steel dual-wall slash-cut tips (clamp-on)
  • Tip dimensions: 2.50-inch inlet, 4-inch outlet, 12 inches long

Engineered for professional-looking results and hassle-free installation, this cat-back system is backed by Gibson's Lifetime Limited Warranty. The aggressive sound profile enhances your driving experience without creating annoying cabin noise.
