Description
Overview
The Flowmaster Flow FX Cat-Back Exhaust System is engineered specifically for the 2021-2026 Ford Bronco equipped with the 2.3-liter or 2.7-liter engine and a 4-door body. Purpose-built to replace the restrictive factory piping from the mid-pipe flange back, this complete cat-back kit delivers a deeper, more assertive exhaust note while unlocking real, measurable performance on one of the most iconic off-road platforms on the market.
At the heart of the system is a Flow FX series muffler that produces a deep exhaust tone with an aggressive to moderate sound level. It hits that sweet spot for drivers who want an unmistakably muscular presence under throttle without droning on the highway. On the dyno, this system produced maximum gains of 12 horsepower and 13 lb-ft of torque measured at the rear wheels.
Built to Perform and Endure
Flowmaster fabricates the Flow FX from 3.00-inch mandrel-bent 409 stainless steel tubing, running from the factory mid-pipe flange all the way back. The mandrel bends preserve consistent diameter through every turn to maximize exhaust flow, while the 409 stainless construction stands up to heat, corrosion, and the demands of the trail. Stepping up from the factory pipe size also means this system is ready to help maximize gains as you add further engine upgrades down the road.
Because the Bronco is built to go off-road, so is this exhaust. The over-axle section is specifically routed to gain an additional 2.0 inches of clearance from the axle on applications running modified suspensions. That extra room allows for better suspension travel in extreme off-road situations, keeping your exhaust protected when the terrain gets serious.
Custom Look, Clean Install
The system finishes with dual 4.00-inch black ceramic-coated tips featuring an embossed logo, adding a purposeful, custom appearance to the rear of the Bronco. All necessary hardware and new hangers are included, and the kit bolts up to factory mounting locations for a straightforward, direct-fit installation.
