Description
Overview
The Flowmaster Outlaw Extreme Cat-back Exhaust System is engineered for drivers who want their truck to be heard. Built specifically for 2009-2014 Ford F-150 trucks equipped with the 3.5L, 4.6L, 5.0L, and 5.4L engines, this complete cat-back setup replaces the restrictive factory piping with a full performance system designed to deliver the most aggressive sound in the Flowmaster lineup. If you like attention and want your F-150 to make a statement, the Outlaw Extreme was purpose-built for you.
At the heart of the system is a 3.00-inch race-proven Outlaw muffler paired with a 3.00-inch mandrel-bent “dump-style” turndown. This combination produces a very deep, aggressive tone that you’ll feel both inside and outside the truck. The mandrel-bent tubing maintains consistent diameter through every bend to promote smooth exhaust flow, while the single tailpipe, turndown-style exit keeps the design clean and purposeful.
Built to Last
Every component is constructed from durable 409S stainless steel for long-term corrosion resistance and rugged reliability, finished in a black pipe color that complements the truck’s underbody. Because the system mounts to the factory hanger locations, it bolts up cleanly without the need for cutting or custom fabrication, making installation straightforward. All of the necessary hardware is included, so this is a quick and easy job you can complete at home.
Fitment
This cat-back system is designed for 2009-2014 Ford F-150 trucks with the 3.5L, 4.6L, 5.0L, and 5.4L engines. It fits both 2- and 4-wheel-drive trucks and all wheelbases, giving F-150 owners flexible coverage across the platform. The muffler is included as part of the kit, though no tip logo, heat shield, or exhaust tip is part of this configuration. It is CARB (California) compliant, carrying Emission Code 5, and ships with a California Proposition 65 warning.
