The Flowmaster® Flow FX Axle-Back Exhaust System is designed for 2021–2025 Ford Bronco trucks with the 2.3L or 2.7L engines. This performance axle-back system features Flow FX mufflers to deliver a deep, aggressive-to-moderate exhaust tone while maximizing performance. Dyno-tested gains of up to +17 hp and +18 lb-ft at the rear wheels make this a perfect upgrade for Bronco enthusiasts.

Constructed from durable 409 stainless steel, the system includes 3.00-inch mandrel-bent tubing for maximum exhaust flow and long-term corrosion resistance. Dual 4.00-inch black ceramic-coated stainless steel tips add a custom, aggressive look to your Bronco. The system installs easily using factory hanger locations and includes all necessary hardware.
