This Flowmaster® Flow FX Direct-Fit Muffler system for the 2021-2026 Ford F-150 trucks with the 2.7, 3.5 or 5.0-liter engines is manufactured using durable 409 stainless steel throughout and features 3.00-inch mandrel bent pipes for optimum exhaust gas flow. A Flowmaster Flow FX Series muffler is used for an aggressive to moderate sound level and maximum performance. Performance increases on the dyno revealed an increase of 18 hp and 14 ft/lbs. at the rear wheels. This system connects directly to the factory dual tail pipes and uses all the existing factory hangers. Includes installation instructions and all necessary hardware for an easy installation that you can do at home. Backed by Flowmaster's One (1) Year Limited Warranty.
