Product Details

The Gibson 315584 Cat-Back Single Side Exhaust System is an aluminized performance exhaust engineered for maximum low-end power delivery. Dyno-tested results demonstrate an average gain of 10–15 horsepower and 15–20 lb-ft of torque, with peak performance occurring in the 1,800–3,000 RPM range — ideal for towing, hill climbing, acceleration, and passing maneuvers.

The system exits cleanly behind the rear tire and is designed to remain noticeably quieter inside the cab compared to competing performance exhaust systems. Bolt-on installation requires no welding, making this a straightforward upgrade with professional-quality results. Backed by Gibson's Lifetime Limited Warranty.

Muffler Specifications:

  • Design: Baffled and chambered muffler — no internal packing
  • Sound profile: Aggressive tone with minimal interior drone
  • Shape: 8 in. round
  • Inlet: 3.00 in. offset
  • Outlet: 3.00 in. offset
  • Length: 24 in.

Exhaust Tip Specifications:

  • Material: Polished T304 stainless steel
  • Style: 4 in. round slash-cut, clamp-on
  • Inlet: 3 in.
  • Outlet: 4 in.
  • Length: 12 in.

The Gibson 315584 delivers a complete cat-back solution combining performance gains, a refined aggressive exhaust note, and durable aluminized steel construction — all in a hassle-free, bolt-on package.
