Product Details

The Gibson Performance 65585 Dual Sport Cat-Back Exhaust System is a complete stainless steel exhaust upgrade engineered to deliver increased low-end power, an aggressive exhaust tone, and a distinctive dual side-exit look — all without welding. Featuring a dual pipe configuration that exits cleanly behind the rear tire, this system adds bold street presence while keeping the exhaust path clear of any tow trailer.

At the heart of the system is Gibson's Superflow baffled and chambered muffler — a no-internal-packing design that minimizes interior drone while producing a deep, authoritative exhaust note. All tubing is crafted from stainless steel with mandrel-bent construction to maintain consistent inner diameter through every bend, maximizing exhaust flow and reducing backpressure.

Key Features:

  • Tubing: 2.25 in. stainless mandrel-bent tubing for unrestricted flow
  • Muffler Design: Baffled & chambered Superflow muffler — no internal packing, minimal interior drone, aggressive sound
  • Muffler Dimensions: 4 x 9 x 18 in. oval body; 3 in. center inlet; 3 in. offset outlet
  • Exhaust Tips: 4 in. polished T304 stainless rolled slash-cut tips — clamp-on design
  • Tip Specifications: 2.25 in. inlet; 4 in. outlet; 12 in. length
  • Exit Position: Behind the rear tire — tow-friendly dual side exit
  • Dyno-tested performance gains: 10–15 HP and 15–20 lb-ft of torque (average)
  • Installation: Bolt-on with all hardware and factory-style hangers included — no welding required
  • Construction: Made in the USA
  • Warranty: Lifetime Limited Warranty

The Gibson 65585 installs using existing factory mounting points for a clean, professional result. Everything needed for installation is included in the kit, making this an ideal bolt-on upgrade for truck and SUV owners seeking more performance and a stronger exhaust note without compromising towing capability.
