S650 MUSTANG PROCHARGER SYSTEMS ARE NOW 50-STATE STREET LEGAL

Mustang owners, the wait is over! ProCharger has received a California Air Resources Board (CARB) Executive Order (EO) for select ProCharger supercharger systems on the 2024-2025 Mustang GT and Dark Horse 5.0L.

That means S650 owners can now bolt on serious ProCharger boost and stay 50-state street legal. If you've been waiting to supercharge your Coyote-powered S650, there's never been a better time to make it happen.

The Executive Order applies to Stage 1 (previously called "High Output") complete ProCharger systems on naturally aspirated 2024-2025 Mustang GT and Dark Horse models. Rated at a maximum of 12 psi of boost, the Stage 1 system uses a 6-rib shared drive. Newer model years are in-process.

The Stage 1 system is a complete, bolt-on package. That includes everything needed to make reliable, intercooled power while keeping your Mustang's emissions equipment working as designed. Your factory mass air flow sensors stays in place, and the system bolts on without permanent modifications to the car.

A CARB Executive Order is the benchmark for emissions compliance on add-on parts. Without one, a supercharged car may not be street legal and can fail an emissions inspection. With this EO, a covered ProCharger system can be installed on a 2024-2025 Mustang GT or Dark Horse and driven every day, in all 50 states.

And you don't give up anything to get there. You still get ProCharger's smooth, linear centrifugal boost, air-to-air intercooling for massive, consistent power, and the hard-hitting pull that makes a ProCharged S650 so addictive to drive.

Have a 2026 Mustang or a bigger build in mind?
