Description
Overview
The Flowmaster Outlaw Extreme Cat-back Exhaust System is engineered for drivers who want the most aggressive exhaust note available for the 2015-2020 Ford F-150. Designed to fit trucks equipped with the 2.7L, 3.3L, or 3.5L EcoBoost, the 3.5L Ti-VCT, and the 5.0L engines, this complete cat-back setup replaces the restrictive factory tubing behind the catalytic converter to unleash a deep, unmistakable sound that gets you noticed on the street and at the job site.
At the heart of the system is a 3.00-inch race-proven Outlaw muffler, paired with mandrel-bent tubing and a single dump-style turndown that exits under the bed. This configuration delivers the ultimate deep and aggressive tone, both inside the cab and outside the truck, making it one of the loudest and most attitude-packed offerings in the Outlaw Extreme series.
Key Benefits
Every component is built for performance and longevity. The system is manufactured from durable 409 stainless steel to stand up to heat, road grime, and the elements, so it keeps looking and sounding great mile after mile. Its silver finish gives the underside of your F-150 a clean, purpose-built appearance.
Installation is straightforward thanks to a slip-on design that connects to the back side of the catalytic converter tubing and mounts using the factory hanger locations. No cutting or custom fabrication is required to hang the system in place, and everything needed for the job is included in the box.
