      Description

      Advanced Exhaust Solution. The Flowmaster Flow FX Direct-Fit Muffler delivers enhanced exhaust performance and sound quality for Ford F-150 trucks. It provides a balance of aggressive and moderate tone while improving horsepower and torque, making it an ideal upgrade for enthusiasts seeking both power and refined exhaust notes. Designed to replace the stock muffler directly, it ensures OEM fitment and reliable operation.

      Construction and Appearance. Crafted entirely from 409 stainless steel, this muffler system offers superior durability and corrosion resistance. The natural finish showcases the robust build quality and features 3.00-inch mandrel bent tubing to maximize exhaust flow. Its oval-shaped muffler body merges performance with a sleek, functional appearance.

      Installation. Installation is straightforward and requires no cutting or welding, as the system connects seamlessly to the factory dual tailpipes using existing hangers. This direct-fit design allows most users to perform the upgrade at home with basic tools and included hardware.

      Warranty. Backed by a one year limited warranty, this exhaust system assures quality and peace of mind.

      Application. This muffler fits 2021 through 2026 Ford F-150 models equipped with 2.7L, 3.5L, or 5.0L non-PowerBoost engines that have factory dual tailpipes. It does not fit PowerBoost models or F-150s with single exhaust configurations within this timeframe.
