Product Details

The Gibson 616515 is a single side cat-back exhaust system engineered to deliver real, measurable performance gains on trucks and SUVs. Dyno-tested to maximize torque and horsepower in the critical 1,800–3,000 RPM range, this system is purpose-built for drivers who demand more from their vehicle — whether towing, hauling, or pushing through the hills.

Key Features:

  • Proven Performance Gains: Average increases of 10–15 horsepower and 15–20 lb-ft of torque, optimized for low-end power delivery
  • SuperFlow Muffler: Baffled and chambered design channels exhaust energy into a deep, aggressive exterior tone while keeping cabin noise levels impressively low
  • Mandrel-Bent Tubing: Maintains a constant diameter through every bend for unrestricted, smooth exhaust flow and minimal backpressure
  • Single Side Exit: Exhaust exits cleanly behind the rear tire for a clean, factory-integrated look
  • Polished Stainless Steel Tip: T304 stainless steel intercooled tip included with a clamp-less connection design for a professional finish
  • Zinc-Plated Hangers & Clamps: All necessary hardware included for a secure, corrosion-resistant installation
  • No Welding or Cutting Required: Direct bolt-on fitment for a clean, hassle-free installation
  • Made in the USA: Engineered and manufactured domestically for quality and reliability
  • Lifetime Limited Warranty: Backed by Gibson's industry-leading warranty coverage

The Gibson 616515 cat-back exhaust system is one of Gibson's top-performing single exhaust configurations, combining genuine power improvements with a deep, commanding exhaust note — and minimal drone inside the cab. It's the ideal upgrade for enthusiasts seeking better acceleration, stronger towing capability, and improved passing power without sacrificing everyday drivability.

Very pleased with the ordering process. Did lots of research on the product I ordered and autoplicity was able to beat the price of any local carrier of this product by $80. Even better that they offered free shipping because it is a heavy item.

Lowest price could find for the same item...
