The Flowmaster Outlaw Cat-Back Exhaust System is engineered for Ford F-150 owners seeking the most aggressive exhaust tone possible while still maintaining a moderate interior sound. Built from durable 409S stainless steel, this bolt-on system delivers powerful performance gains, improved exhaust flow, and the unmistakable Flowmaster sound.

This system features a 3.00-inch mandrel-bent inlet tube feeding into a Super 10 Series muffler, followed by dual 2.50-inch mandrel-bent tailpipes. The exhaust is finished with large 4.00-inch black ceramic-coated stainless steel tips for a bold, modern look. You can choose between rear exit or side exit tailpipe configurations—perfect whether you tow or want a more traditional muscle-truck appearance.

This Outlaw system fits all 2WD and 4WD 2015–2020 Ford F-150 models in all available wheelbases, except Standard Cab / Short Bed configurations. Designed for easy installation, the kit includes all required hardware and utilizes factory hanger locations.
