Flowmaster introduces our FlowFX stainless steel cat-back exhaust systems for the 2021-2022 Ford F-150 trucks with the 2.7, 3.5, and 5.0-liter engines. These systems use a FlowFX series muffler for an aggressive to moderate sound level and increased performance. Mandrel bent 409 stainless steel tubing allows for maximum exhaust flow and durability. The systems use larger 4.00-inch and 4.50-inch black ceramic-coated tips for a custom look. Max dyno gains of 13 hp and 16 lb-ft at the rear wheels with the 718115 kit. All of the necessary hardware is included, and factory-mounting locations are used for an easy installation. Backed by Flowmaster's Lifetime Limited Warranty.
