Product Details

The Gibson Performance Exhaust Dual Sport Cat-Back Exhaust System is engineered for truck and SUV owners who want aggressive styling without compromising towing functionality. This unique system exits behind the rear tire rather than at the rear bumper, delivering a distinctive appearance that stands out on the street or off-road while keeping exhaust gases away from trailers during towing.

Key Features:

  • Dual side-exit design routes exhaust behind rear tire for unique styling and towing convenience
  • Bolt-on installation requires no welding or specialized tools for hassle-free setup
  • Deep, authoritative exhaust tone with minimal cabin noise intrusion
  • Dyno-tested performance gains of 18-20 horsepower and 15-20 lb-ft of torque
  • Cat-back design replaces exhaust from catalytic converter to exit point
  • Backed by Gibson's Lifetime Limited Warranty for long-term confidence

This complete cat-back system delivers professional-quality results with straightforward installation. The side-exit configuration provides both functional and aesthetic benefits, making it an ideal choice for truck and SUV enthusiasts who demand performance, style, and practicality.

best price

This place is AWESOME!!! Thanks!!!

smooth

Great prices and fast shipping. Will use this company many more times in the future.

I ordered a new battery for my Harley. I wanted a battery that would last and be of good quality. I bought a Odyssey PC545 battery it stats stat it will last up to 8 years and is military grade. My package arrived quick and in good shape. My order number is #5600. Thanks

I'm a little concerned. The Fabtech part number doesn't match the correct description. I need the impact tube rear mount not the bushing kit. I talked to a representative and he said if I used the Fabtech number I would get the correct part.
