    Flowmaster 817674 Features:

    The new Flowmaster American Thunder cat-back exhaust system for the 2007-2018 Jeep Wrangler JK is perfect for the person looking for maximum performance and off-road ground clearance. This system replaces the factory transverse muffler and relocates the Super HP-2 muffler behind the factory catalytic converter, providing a moderate to aggressive sound level. The system features a mandrel-bent 2.50-inch stainless steel tailpipe with a 3.00-inch polished stainless steel tip tucked up high under the rear bumper for maximum clearance. Fits both 2 and 4 door models with either the 3.8L or 3.6L engines. Because the tailpipe is tucked up so high, an aftermarket metal bumper is recommended. The exhaust system is covered by our Lifetime Limited Warranty and includes all necessary parts and hardware for an easy installation you can do at home.

    • Provides Maximum Clearance for Off-Road Driving
    • Super HP2 Laminar Flow Technology
    • Uses the Factory Hanger Locations
    • Stainless Steel Construction
    • Quick and Easy Installation

      • The Classic Sound of Flowmaster

The mufflers are tuned to deliver more power, torque, throttle response, and mileage. With easy fitment in mind, each system has mandrel-bent tubing for maximum performance and flow; and includes all necessary parts and hardware for installation.
