Mild Flowmaster Sound. If you're looking for a cat-back system that gives your mighty 5.4L powered F-150 an exhaust note that won't attract unwanted attention, but will still bark when stepping on the gas, then the Force II Aluminzed Steel Cat-Back System from Flowmaster is for you. This cat-back system features mandrel bent tubing that will improve your truck's exhaust flow for an increase in mileage, power and throttle response. With the included Super 50 Series muffler, this cat-back system delivers a mild to moderate exhaust note that won't be overbearing especially when you're pulling a trailer. Best of all, Flowmaster includes exit pipes that allow you to mount the exhaust tips at the rear of your truck or behind your rear passenger tires.

Quality Construction. Proudly made in the USA, this Flowmaster Force II Cat-Back Exhaust is constructed from 3 in. inlet / dual 2.5 in. outlet mandrel bent aluminized steel tubing for strength and corrosion resistance. This cat-back exhaust features a single inlet / dual outlet Super 50 Series Muffler that connects to a pair of polished 3 in. exhaust tips for great looks and sound. As an added bonus, the tips are embossed with the Flowmaster logo for true custom styling.

Bolt-On Installation. Flowmaster engineered this kit to be a direct upgrade replacement for your F-150 stock exhaust. All of the necessary hardware is included and installs easily with basic hand tools, with no extra modifications to your F-150. Depending on your cab and bed size, some minor cutting to the piping may be required.

Application. This Flowmaster Force II Aluminized Steel Cat-Back Exhaust System is designed to fit on all 2004-2008 F-150s powered by the 5.4L V8 engine.
