    Better Exhaust Flow with More Power Where It's Needed

    Gibson Cat-Back Exhaust Systems deliver more power from 2000-4000 RPM than other exhaust systems improving exhaust flow and power where you need it! Turbulence exists at every point the exhaust gas ''pulse'' enters or exits an exhaust component. Gibson reduces turbulence to the absolute minimum with their patented Superflow™ design. The dual sport system will be about 5-8 decibels louder than a stock system. yet produces a nice deep throaty sound outside and slightly above decibels inside the cab. All Gibson Exhaust Systems are made with mandrel bent tubing for the least restriction possible. Not only does this reduce restriction, but creates a consistent flow throughout the system.

    Dual Sport Exhaust
    If you're looking for that awesome street truck look and want to keep the exhaust from affecting your tow trailer or vehicle, this dual cat-back exhaust is for you. Designed for hassle-free, bolt-on installation with professional-looking results while providing a powerful aggressive deep exhaust tone. Dyno tested to ensure increased horsepower and torque without annoying in-cab noise. Average gains: 10-15 horsepower and 15-20 ft/lbs torque. Fuel economy may improve as your engine becomes more fuel efficient.

    Features
  • Increased Horsepower & Torque
  • All-Welded Design for Maximized Airflow
  • No Packing to Blow Out or Deteriorate
