Unleash extreme levels of sound and performance on your 2015–2020 Ford F-150 with the Flowmaster® Outlaw® Extreme Cat-Back Exhaust System. Engineered for drivers who want maximum volume and an unmistakably aggressive tone, this system delivers the loudest and deepest Outlaw exhaust note available for the F-150 platform.

The Outlaw Extreme system slips directly onto the back side of the catalytic converter tubing and features a race-proven 3.00-inch Outlaw muffler combined with a mandrel-bent single turndown dump exit positioned under the bed. This design produces a raw, powerful tone both inside and outside the truck—perfect for extreme sound enthusiasts.

Constructed from durable 409 stainless steel, the system uses factory hanger locations for a fast, no-fabrication installation. All required hardware and detailed installation instructions are included for a straightforward at-home setup. As with all Flowmaster Outlaw Extreme systems, expect maximum volume, maximum attitude, and maximum presence.
