    Our Force II® cat-back exhaust system for 2009-2014 Ford F-150 trucks is perfect for the person looking for a mild to moderate interior tone with a moderate exterior sound level and all the performance benefits you expect from Flowmaster®. This bolt-on exhaust comes with your choice of either dual out the rear under the bumper for a muscular look, or dual out the sides behind the rear wheels, which is ideal for towing. Features include a stainless steel mandrel-bent 3.00-inch inlet tube flowing into a Super 50™ Series performance muffler exiting into dual 2.50-inch mandrel-bent tailpipes for maximum performance and sound. The tailpipes clear the factory spare tire and feature large 3.50-inch polished stainless steel tips. The system is covered by our Lifetime Limited Warranty and includes all necessary parts and hardware for easy installation you can do at home. Note: Fits 2/4 wheel drive and all wheelbases.
