Product Details

The Gibson 619900 Cat-Back Single Side Exhaust System is engineered for drivers who demand improved performance without sacrificing drivability. Featuring a bolt-on design that requires no welding, this stainless steel exhaust exits cleanly behind the rear tire for a clean, factory-quality appearance with a noticeable performance upgrade.

Dyno-tested results demonstrate peak torque and horsepower gains in the critical low-end RPM range of 1,800–3,000 RPM, where everyday driving, towing, and hauling demand the most. Expect average gains of 10–15 horsepower and 15–20 lb-ft of torque — making this system ideal for towing, hill climbing, passing, and acceleration.

Key Features:

  • Exits behind the rear tire for a clean, tucked installation
  • Quieter in-cab sound level compared to competing performance exhaust systems
  • Aggressive exterior exhaust note without excessive interior drone
  • Hassle-free, bolt-on installation — no welding required
  • Backed by Gibson's Lifetime Limited Warranty

  • Shape: 8 in. round
  • Inlet: 3.00 in. offset
  • Outlet: 3.00 in. offset

Constructed from durable T304 polished stainless steel, the Gibson 619900 is built to resist corrosion and maintain its finish over the long haul. Whether you're looking for more pulling power on the job or a more spirited driving experience on the highway, this cat-back system delivers real, measurable results right out of the box.
