Product Details

The Gibson Performance 618705 is a stainless steel cat-back single exhaust system engineered and dyno-tested to deliver real, measurable performance gains. Featuring a swept-side exit behind the rear tire, this system is purpose-built for improved acceleration, hill climbing, towing, and passing power — with a deep, aggressive exhaust tone that stays remarkably quiet inside the cabin.

At the heart of this system is Gibson's Superflow Muffler — a fully welded, baffled and chambered design with no internal packing. This construction maximizes volume efficiency and unrestricted flow, minimizing interior drone while producing a bold exterior sound. Tubing is mandrel-bent stainless steel to maintain consistent exhaust flow through every bend, reducing backpressure for peak efficiency.

Performance Specs:

  • Dyno-verified horsepower gains averaging 10–15 HP
  • Torque gains averaging 15–20 lb-ft
  • Maximum power delivery in the low-end RPM range (1,800–3,000 RPM)
  • Improved fuel economy as a result of reduced backpressure

Muffler Specs:

  • Style: Baffled and chambered Superflow design — no internal packing
  • Body: 6 in. round
  • Inlet: 2.50 in. offset
  • Outlet: 2.50 in. offset
  • Body Length: 19 in.

Tip Specs:

  • Style: Round slash-cut, polished T-304 stainless steel, clamp-on
  • Inlet: 2.50 in.
  • Outlet: 3 in.
  • Length: 8 in.

Installation & Warranty:

  • True bolt-on installation — no drilling or welding required
  • Includes all hardware and factory-style zinc-plated hangers
  • Made in the USA
  • Backed by Gibson's Lifetime Limited Warranty
