The system fits both 2 and 4 wheel drive trucks, and all wheelbases. Constructed with durable 409S stainless steel and uses the factory hanger locations, so installation is a breeze. The system is covered by our Lifetime Limited Warranty and includes all of the necessary hardware for a quick and easy installation you can do at home. 2009-2014 Ford F-150 trucks with 3.5L, 4.6L, 5.0L and 5.4L engines. - Aggressive sound Flowmaster Outlaw Extreme Cat-back Exhaust System
