The Flowmaster® Outlaw® Cat-Back Exhaust System is designed for 2021–2025 Ford F-150 trucks equipped with 2.7L, 3.5L, and 5.0L engines. This system delivers aggressive sound levels both inside and outside the truck while providing the performance gains expected from Flowmaster.

Constructed from durable 409 stainless steel, the system features 3.00-inch mandrel-bent tubing flowing into a Super 10™ Series muffler for a deep, powerful tone. Dual 3.00-inch tailpipes offer two exit options: straight out the back under the bumper or exiting behind the rear wheels—ideal for towing applications. The tailpipes are finished with large 4.00-inch black ceramic-coated stainless steel tips for a custom, aggressive look.

This bolt-on system installs easily using factory hanger locations and includes all necessary hardware. Covered by Flowmaster’s Lifetime Limited Warranty, the Outlaw Cat-Back Exhaust combines durability, performance, and a bold appearance.
