Product Details

The Gibson 615571L Cat-Back Single Exhaust System is Gibson's top-performing cat-back solution, engineered to maximize low-end power delivery. Featuring mandrel-bent stainless steel tubing and a baffled Superflow muffler design, this system delivers real, dyno-proven performance gains while keeping cabin noise lower than competing performance exhaust systems. The exhaust exits cleanly behind the rear tire for a clean, factory-integrated look with aggressive performance character.

Performance Highlights:

  • Dyno-proven horsepower gains of 10–15 HP and 15–20 lb-ft of torque
  • Maximum power delivery at low-end RPM range (1,800–3,000 RPM)
  • Optimized for acceleration, towing, hill climbing, and passing power
  • Quieter interior cabin noise compared to other performance exhaust systems

Muffler Specifications:

  • Baffled and chambered Superflow muffler design
  • No internal packing for long-term durability
  • Minimal interior drone with aggressive exterior exhaust tone
  • 8 in. round body; 3.00 in. center inlet; 3.00 in. center outlet; 24 in. length

Tip Specifications:

  • 3.5 in. polished T304 stainless steel round slash-cut tip
  • Clamp-on installation; 3 in. inlet, 3.5 in. outlet, 12 in. length

Installation & Hardware:

  • Complete bolt-on installation — no welding required
  • Includes all hardware and factory-style hangers
  • Exit position: behind the rear tire
  • Backed by Gibson's Lifetime Limited Warranty
