This Flowmaster® Outlaw® cat-back exhaust system is for the 2021-2025 Ford F-150 trucks with the 2.7L, 3.5L and 5.0L engines and offers maximum sound levels both inside and outside of the truck, with all of the performance benefits that you would expect from Flowmaster. This bolt-on emissions-legal system features all mandrel-bent 409 stainless steel 3.00-inch tubing flowing into a Super 10™ Series muffler and exiting into large 3.00-inch dual tailpipes for maximum sound and performance.

Designed for an easy fit, this system includes all necessary parts and hardware for installation. Note: Fits 2/4 wheel drive.
