    Breakdown of Included Items

    Flowmaster 717976 FlowFX Extreme Cat-Back Exhaust System Features:

    • 11 Horsepower and 15 ft./lbs. of torque increase at rear wheels
    • Powerful deep sound inside & outside the vehicle
    • Dump style exhaust tip after the muffler eliminates over-the-axle routing
    • Greatly improved ground clearance and departure angle for serious off-roading
    • Attaches with included hardware to factory hanger locations for easy install

    Emissions: This part is legal for sale or use on Emissions Controlled Vehicles, Uncontrolled (Non-Emissions Controlled) Vehicles, and Racing Use Only Vehicles because it does not affect vehicle emissions and is not covered by emissions regulations.

    • Extreme Off-Road, High-Clearance Exhaust Upgrade 

      Flowmaster FlowFX Extreme Series Exhaust Kits give your vehicle the exhaust sound you want without offending the entire neighborhood. These dump-style exit systems eliminate the tailpipe after the rear axle for better performance and ground clearance. Mandrel-bent, 16-gauge, 409S stainless steel ensures durability and corrosion resistance, and the 3.0 in. diameter tubing allows maximum flow.
