Description
Overview
The Flowmaster Outlaw Exhaust System Kit is engineered specifically for the 2021-2026 Ford F-150 equipped with the 2.7L, 3.5L, or 5.0L engine and factory dual exit exhaust. Designed to fit both PowerBoost hybrid and non-hybrid models, this cat-back exhaust system transforms your truck’s sound and performance with a proven, bolt-on package that uses the factory hangers for a genuinely straightforward installation. If you’ve been searching for a performance exhaust that delivers real gains without compromising fit, this Flowmaster kit is built to answer that call.
At the heart of the kit is the Super 10 Series muffler, part of Flowmaster’s aggressive Outlaw exhaust series. This 10 Series muffler measures 12.20 inches in overall length with a center inlet and dual 3.00-inch outlet, producing an aggressive-to-moderate exhaust tone that gives the F-150 a bold, unmistakable voice. On the dyno, this exhaust system produced maximum gains of 18 horsepower and 15 lb-ft of torque measured at the rear wheels.
Built to Flow and Last
Every exhaust pipe in this system is constructed from 3.00-inch mandrel-bent 409 stainless steel tubing. Mandrel bending keeps the diameter consistent through every bend, maximizing exhaust flow and airflow efficiency, while 409 stainless steel delivers long-term durability against heat and corrosion. The silver pipe finish and black muffler complete a clean, purposeful look under the truck.
Custom Style at the Exit
The dual tail pipe layout is finished with dual 4.50-inch black ceramic-coated stainless steel tips featuring an embossed logo. These tips add a custom, aggressive appearance that matches the tone of this catback exhaust and sets your F-150 apart from a factory setup.
