The new Flowmaster Outlaw Extreme Cat-back exhaust system is for 2009-2014 Ford F-150 trucks with the 4.6L, 5.0L, and 5.4L engines. Do you like attention and want to be heard? These kits deliver the ultimate in aggressive sound by using a 3.00 in. race-proven Outlaw muffler and a 3.00 in. mandrel-bent dump-style turndown for a very deep aggressive sound both inside and outside the truck. 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.
