EXCERPT -

Roush Performance has just released that its 2021 Stage-III Mustang, with either 750 or 775 horsepower has now received full, 50-state emissions compliance. This puts Roush Performance as a fully compliant new vehicle manufacturer. This not only ensures the vehicle emissions systems will perform to OEM standards for tailpipe, evaporative, and diagnostics for a minimum of 150,000 miles, but also offers peace of mind to enthusiasts who want to own a highly modified car but do not want to run the risk of running afoul of the law and the potential of incurring emissions-related fines.
