The Flowmaster Outlaw Cat-Back Exhaust System is designed to deliver maximum performance, aggressive sound, and improved off-road capability for your 2021–2025 Ford Bronco 4-door. Built with 3.00-inch mandrel-bent 409 stainless steel tubing, this system increases exhaust flow and durability while providing dyno-proven gains of up to 6 horsepower and 7 lb-ft of torque at the rear wheels.

The over-axle routing has been engineered to create an additional 2.0 inches of suspension clearance, ideal for Broncos equipped with modified suspension systems or used in demanding off-road environments. The Outlaw-style muffler produces a deep, aggressive exhaust tone that enhances the Bronco’s character without compromising performance.

Finishing the system are dual 4.00-inch black chrome stainless steel tips that provide a bold, custom appearance. Installation is straightforward using factory-style hangers and the included hardware. This system is backed by Flowmaster’s Lifetime Limited Warranty for long-lasting confidence.
