Product Details

The Gibson 615634 Cat-Back Single Exhaust System is a stainless steel, bolt-on performance upgrade engineered to deliver strong low-end power gains and an aggressive exhaust tone. Built with mandrel-bent tubing and a baffled/chambered Superflow muffler design, this system is optimized to reduce backpressure and maximize torque and horsepower output throughout the low-to-mid RPM range.

Dyno-tested results demonstrate peak torque and horsepower gains in the 1,800–3,000 RPM range, with average increases of 10–15 HP and 15–20 lb-ft of torque. The single side-exit configuration routes exhaust behind the rear tire for a clean, functional finish with minimal interior drone — quieter in the cab than competing performance exhaust systems.

Muffler Specifications:

  • Design: Baffled & Chambered Superflow™ Muffler — no internal packing
  • Sound Profile: Aggressive exterior tone, minimal interior drone
  • Body: 4 x 9 x 18 in. oval body
  • Inlet: 3 in. center inlet
  • Outlet: 3 in. offset outlet

Tip Specifications:

  • 4 in. polished T304 stainless steel rolled slash-cut tip
  • Clamp-on installation
  • Inlet: 3 in. | Outlet: 4 in. | Length: 12 in.

System Features:

  • 3 in. stainless steel mandrel-bent tubing for unrestricted exhaust flow
  • Single side-exit — exits behind the rear tire
  • Includes all hardware and factory-style hangers for bolt-on installation
  • No welding or drilling required
  • Proudly made in the USA
  • Backed by a Lifetime Limited Warranty

This complete cat-back exhaust kit includes everything needed for a straightforward, professional-quality installation using existing factory mounting points. It is an ideal performance upgrade for drivers seeking improved acceleration, towing capability, and passing power without sacrificing daily drivability.
