Product Details

The Gibson 18800 Cat-Back Single Side Exhaust System is engineered to deliver maximum performance gains where you need them most — at low RPM. Built for drivers who demand improved acceleration, superior hill-climbing capability, and enhanced towing and passing power, this aluminized exhaust system is Gibson's top-performing cat-back solution.

Dyno-tested results confirm impressive gains of 10–15 horsepower and 15–20 lb-ft of torque, with peak output concentrated in the critical 1,800–3,000 RPM range — ideal for hauling and towing applications. The exit position behind the rear tire keeps cabin noise to a minimum while still delivering an aggressive exhaust note.

  • Baffled and chambered muffler design
  • No internal packing for long-term durability
  • Minimal interior drone for a quieter cab experience
  • Aggressive exterior sound profile
  • Shape: 6 in. Round
  • Inlet: 2.50 in. Offset
  • Outlet: 2.50 in. Offset
  • Length: 24 in.

Exhaust Tip Details:

  • Round Slash-Cut tip style
  • Clamp-on installation
  • Inlet: 2.50 in.

Key Features:

  • 100% bolt-on installation — no welding required
  • Professional-quality fit and finish
  • Aluminized steel construction for corrosion resistance
  • Exits behind the rear tire for a clean, factory-style appearance
  • Backed by a Lifetime Limited Warranty
