2021-2026 Ford Bronco with 2.3L and 2.7L Ecoboost engines. Fits 2 & 4-wheel drive. Fits 4 door models only. For 2 door models see part # 718146. Note: 2021-2024 Bronco cat-back systems will have lower peak dyno results on stock applications when compared to our axle-back systems. This is because the larger 3.0-inch tubing after the factory mid-pipe connection in the cat-back system is optimized for vehicles with additional engine modifications such as tuners, cold air intakes, etc., and is less restrictive when used on higher horsepower applications.

Flowmaster introduces our Flow FX cat-back exhaust system for the 2021-2026 Ford Bronco with the 2.3 or 2.7-liter engine and 4 doors. This system uses a Flow FX style muffler for a deep exhaust tone with an aggressive to moderate sound level and increased performance. Maximum dyno gains of 12 hp and 13 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 ceramic coated 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.
