Product Details

The Gibson 615625 Cat-Back Single Side Exhaust System is engineered for maximum low-end performance, delivering impressive gains in torque and horsepower right where you need them most — between 1,800 and 3,000 RPM. Dyno-tested to produce average gains of 10–15 horsepower and 15–20 lb-ft of torque, this system is purpose-built for drivers who demand more pulling power for towing, hill climbing, acceleration, and passing.

Designed as a true bolt-on upgrade, the Gibson Single Side system requires no cutting, no welding, and no fabrication. The exhaust exits cleanly behind the rear tire, and the cab-quiet design keeps interior drone to a minimum — making it one of the quietest performance exhaust systems available without sacrificing an aggressive exterior tone.

Muffler Specifications:

  • Baffled and chambered muffler design with no internal packing
  • Minimal interior drone with an aggressive exterior sound profile
  • Muffler body: 8 x 11 x 24 in. oval
  • Inlet: 3.50 in. offset
  • Outlet: 3.50 in. offset

Exhaust Tip Specifications:

  • 4 in. polished T304 stainless steel round slash-cut tip
  • Clamp-on installation
  • Tip inlet: 3.50 in.
  • Tip outlet: 4 in.
  • Tip length: 12 in.

Additional Features:

  • Constructed from corrosion-resistant T304 stainless steel
  • Hassle-free bolt-on installation — no welding required
  • Professional OEM-style fitment and finish
  • Backed by Gibson's Lifetime Limited Warranty

Whether you're looking to improve everyday drivability or maximize performance under load, the Gibson 615625 cat-back exhaust system is the ideal single-exit upgrade for power, sound, and lasting durability.
