Flowmaster introduces our Outlaw cat-back exhaust system for the 2021-2026 Ford F-150 with the 2.7, 3.5, or 5.0-liter engine and factory dual exit exhaust. The exhaust kit fits PowerBoost and non-hybrid models. This system uses the Super 10 series muffler for an aggressive exhaust tone and increased performance. Maximum dyno gains of 18 hp and 15 lb-ft were measured at the rear wheels. 3.00-inch mandrel bent 409 stainless steel tubing is used to maximize exhaust flow and durability. Dual 4.50-inch black ceramic coated stainless steel tips are used to add a custom look to the truck. All the necessary hardware is included and factory mounting locations are used for an easy installation. Backed by Flowmaster's Lifetime Limited Warranty.
