Product Details

The Gibson 5662 Dual Extreme Cat-Back Exhaust System is engineered for truck owners who demand serious performance and an aggressive exhaust presence. This dual exit system routes behind the rear tires at a bold angle, delivering a deep, commanding exhaust note without excessive interior drone.

Performance & Sound:

  • Dyno-tuned and application-tested for maximum street performance gains
  • Average horsepower gains of 15–20 HP with improved throttle response
  • Baffled and chambered SuperFlow muffler design with minimal internal packing for an aggressive tone and reduced interior drone
  • Improves exhaust flow by eliminating factory system restrictions

Construction & Materials:

  • Heavy-duty aluminized mandrel-bent tubing for consistent flow and long-term durability
  • Mandrel bends resist cracking and kinking for extended service life
  • Polished T304 stainless steel rolled slash-cut tips — 4 in. outlet, 2.25 in. inlet, 12 in. length
  • Tubing diameter: 3 in. headpipe / 2.25 in. secondary

Installation & Warranty:

  • Direct bolt-on, clamp-on cat-back installation — no cutting or welding required
  • Includes all necessary installation hardware
  • Backed by Gibson's Lifetime Limited Warranty
  • Made in the USA

The Gibson 5662 Dual Extreme system is a complete cat-back exhaust upgrade that pairs bold dual rear-exit styling with real, measurable performance improvements straight out of the box.
