Flowmaster 817981 Outlaw Cat-Back Exhaust System

This Flowmaster® Outlaw® cat-back exhaust system is for the 2021-2026 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. The system comes with two sets of tailpipe exits for you to choose from, either straight out the back under the bumper, or exiting behind the rear wheels, which is ideal for towing applications. The tailpipes are finished off with a pair of large 4.00-inch black ceramic-coated stainless steel tips and the exhaust system is covered by our Lifetime Limited Warranty. Designed for an easy fit, this system includes all necessary parts and hardware for installation. Note: Fits 2/4 wheel drive.
