Product Details

The Gibson Performance Exhaust 5650 Dual Sport Cat-Back Exhaust System delivers a powerful, authoritative exhaust tone while giving your truck or SUV a distinctive look. Designed with a dual-exit configuration that routes exhaust behind the rear tires, this system keeps the exhaust path clear of tow trailers — making it an ideal upgrade for both street driving and off-road use.

Built from aluminized steel with mandrel-bent tubing, the 5650 features a 3.5-inch headpipe and 3-inch dual tailpipes for consistent, unrestricted exhaust flow. Dyno-tested for real-world performance, this system delivers average gains of 10–15 horsepower and 15–20 lb-ft of torque. The baffled and chambered muffler design produces an aggressive, deep exhaust note while keeping interior drone to a minimum.

Key Features:

  • Cat-back dual-exit design — exhaust exits behind the rear tire
  • Aluminized steel construction with mandrel-bent tubing for long-lasting durability
  • 3.5-inch headpipe with 3-inch dual mandrel-bent tailpipes
  • Baffled and chambered muffler — aggressive sound with minimal interior drone
  • Muffler specs: 8 in. round body; 3.50 in. center inlet; 3.00 in. dual outlet; 24 in. length
  • Includes 4 in. polished T304 stainless steel rolled slash-cut tip (clamp-on): 3 in. inlet, 4 in. outlet, 12 in. length
  • Zinc-plated factory-style hangers and all necessary hardware included
  • No welding required — complete bolt-on installation
  • Dyno-tested for verified horsepower and torque gains
  • Backed by Gibson's Lifetime Limited Warranty

The Gibson 5650 is a straightforward bolt-on upgrade that installs with factory-style hangers and all included hardware — no welding or fabrication needed. Whether you're towing, hitting the trail, or cruising the street, the Dual Sport system adds performance and a clean dual-exit look without compromising utility.
