    FLOWMASTER MUFFLERS 817757 Features:

    Our Force II® line of exhaust systems are engineered as our quietest offerings, but will wake up your vehicles sound and power over the factory O.E. exhaust. You can generally expect a noticeable sound increase with a deep performance tone outside the vehicle, yet minimal interior drone in the cab area while cruising down the road enjoying all the performance benefits you've come to expect from Flowmaster®. This bolt-on emissions-legal cat-back system features full stainless steel construction, uses the factory hanger locations, 50 Series HD™ performance muffler with large 4.00-inch internals and dual 3.00-inch mandrel bent tailpipes offering two tailpipe exits in one kit. Choose your tailpipe exit either located under the rear bumper for an aggressive dual exhaust look, or exiting out the sides behind the rear tires to prevent blowing exhaust on your boat or trailer when towing. The system is finished off with a pair of large 4.00-inch polished logo embossed stainless steel tips for a modern look and includes instructions and all necessary hardware for an easy at home installation. Note: Fits 2/4 wheel drive and all wheelbases.
