The Flowmaster Flow FX Dual Mode Muffler with Active Exhaust Valve transforms your vehicle’s exhaust system with the versatility of dual personalities. Designed as a direct-fit replacement for vehicles equipped with a factory dual-exit exhaust and 5.7L engine, this system blends refined performance tone with rowdy aggression—all controlled wirelessly.

At its core is Flowmaster’s W.A.V.E. Technology™ (Wireless Active Valve Exhaust™), which allows you to switch between modes with just the push of a button. In normal mode, the Flow FX performance muffler provides a deep, straight-through performance tone that enhances driving pleasure without overwhelming interior volume.

Activate the valve, and the exhaust is redirected through a high-flow Power Chamber® and a 3.00-inch turndown dump-style tailpipe, releasing a raw, aggressive sound that announces your presence. Perfect for off-road or show environments, this feature brings unmatched flexibility to your driving experience.

Constructed from mandrel-bent 16-gauge stainless steel for superior strength and flow, this system includes a wireless actuator motor, control unit, two remotes, wiring, and detailed installation instructions. It’s a complete bolt-on upgrade with no cutting or welding required.
