Product Details

The Gibson 315628 Single Side Exhaust System is a premium cat-back performance exhaust engineered to deliver maximum low-end power, improved towing capability, and enhanced throttle response. Designed as a true bolt-on upgrade, this system requires no welding and installs with professional-quality results in a fraction of the time of custom exhaust work.

Gibson's proprietary exhaust design is optimized for real-world driving conditions, with dyno-tested performance gains focused in the critical 1,800–3,000 RPM power band — exactly where you need torque for acceleration, hill climbing, towing, and passing. Average gains of 18–21 horsepower and 20–22 lb-ft of torque make this one of the most effective bolt-on performance upgrades available.

Key Features:

  • Single side exit exhaust routed behind the rear tire
  • Dyno-proven low-end torque and horsepower gains (1,800–3,000 RPM)
  • Average gains of 18–21 HP and 20–22 lb-ft torque
  • Quieter in-cab sound level compared to competing performance exhaust systems
  • 100% bolt-on installation — no welding required
  • Professional fitment and finish right out of the box
  • Backed by Gibson's Lifetime Limited Warranty

Whether you're towing heavy loads, tackling steep grades, or simply want more power on demand, the Gibson 315628 delivers proven performance gains with a clean, factory-style installation. The exit-behind-rear-tire routing keeps exhaust gases away from the vehicle and provides a clean, finished look.

Everything worked well for me with this order. The only funny thing is that Autoplicity claimed that the part I was ordering will not fit make and model of my car, despite the fact that I was ordering manufacturer part number specific to my vehicle.
