Product Details

The Gibson 315629 Single Side Exhaust System is a high-performance cat-back exhaust engineered to maximize power output where it matters most. Designed for drivers who demand more from their vehicle, this system delivers proven dyno-tested horsepower and torque gains with a clean, professional finish and a hassle-free bolt-on installation.

Performance Highlights:

  • Average horsepower gains of 18–21 HP
  • Average torque gains of 20–22 lb-ft
  • Peak power gains delivered in the low-end RPM range (1,800–3,000 RPM) for improved real-world drivability
  • Ideal for acceleration, hill climbing, towing, and passing maneuvers

Design & Construction:

  • Exit position behind the rear tire for a clean, factory-integrated appearance
  • Quieter in-cab exhaust note compared to competing performance exhaust systems
  • Bolt-on installation — no welding required
  • Professional-grade fit and finish straight out of the box

Warranty:

  • Backed by Gibson's Lifetime Limited Warranty

Whether you're hauling a heavy load or looking for stronger throttle response in everyday driving, the Gibson 315629 delivers the low-end grunt and exhaust flow improvement your vehicle needs. Gibson's single-exit design keeps noise levels comfortable inside the cab while still producing the performance sound and gains expected from a true performance exhaust upgrade.
