Product Details

The Gibson 618813 is a cat-back single exhaust system crafted from polished T304 stainless steel, engineered to maximize low-end performance for improved acceleration, towing, hill climbing, and passing power. Dyno-tested results confirm average gains of 10–15 horsepower and 15–20 lb-ft of torque, with peak output delivered in the critical 1,800–3,000 RPM range where trucks and SUVs need it most.

Key Features:

  • 2.5-inch mandrel-bent stainless steel tubing for consistent, unrestricted exhaust flow throughout the system
  • Baffled and chambered SuperFlow muffler — no internal packing to blow out, minimizes interior drone while delivering an aggressive exterior tone
  • 6-inch round muffler with 2.5-inch offset inlet and 2.5-inch offset outlet, 24-inch body length
  • 3.5-inch polished T304 stainless round slash-cut tip (2.5-inch inlet, clamp-on, 12-inch length)
  • Exits behind the rear tire for a clean, factory-integrated look
  • Includes all hardware and factory-style hangers for a hassle-free, bolt-on installation — no welding required
  • Quieter in-cab experience compared to other performance exhaust systems
  • Backed by a Lifetime Limited Warranty

This direct-fit cat-back system is designed for a straightforward installation with professional results. The stainless steel construction ensures long-term durability and corrosion resistance, while the polished tip adds a finished, high-performance appearance. UPC: 677418027006.
