Flowmaster introduces our Outlaw cat-back exhaust system for the 2021-2025 Ford Bronco with the 2.3 or 2.7-liter engine and 4 doors. This system uses an Outlaw style muffler for an aggressive exhaust tone and increased performance. Maximum dyno gains of 6 hp and 7 lb-ft. were measured at the rear wheels. 3.00-inch mandrel bent 409 stainless steel tubing is used from the factory mid-pipe flange back to maximize exhaust flow and durability. This step up from the factory pipe size will help maximize gains from additional engine upgrades. The over-axle section is also routed to help gain an additional 2.0-inches of clearance from the axle when used on applications with modified suspensions. This allows for better suspension travel when used in extreme off-road situations. Dual 4.00-inch black chrome tips are used to add a custom look to this iconic vehicle. All of the necessary hardware is included and factory mounting locations are used for an easy installation. Backed by Flowmaster's Lifetime Limited Warranty.
