FlowFX Cat-Back Exhaust | Dual Exit | 409 Stainless Steel | SKU: 718122

Upgrade your Bronco with the FLOWMASTER FlowFX Cat-Back Exhaust System (718122). Designed specifically for the 2021–2026 Ford Bronco 2.3L and 2.7L EcoBoost 4-Door models, this system delivers deep aggressive sound, improved exhaust flow, and increased suspension clearance for both daily driving and serious off-road adventures.

Featuring a high-performance FlowFX straight-through muffler, this cat-back system produces a deep aggressive exhaust tone with an aggressive-to-moderate sound level while maintaining comfortable drivability. The system is dyno-tested with gains of up to 12 horsepower and 13 lb-ft of torque at the rear wheels.

Constructed from 3-inch mandrel-bent 409 stainless steel tubing, the 718122 maximizes airflow and long-term durability. The over-axle section is specifically routed to provide an additional 2 inches of suspension travel clearance on modified suspension setups, making it ideal for lifted Broncos and off-road builds.

The system is finished with dual 4-inch black ceramic-coated stainless steel exhaust tips for an aggressive custom appearance that perfectly complements the Bronco’s rugged styling.
