Roush 2021 Stage 3 Mustang Earns 50-State Emissions Certification

50-State Emissions Certification For Roush Stage 3 Mustang

The 775 horsepower, 2021 ROUSH Stage 3 Mustang passes the rigorous emissions compliance testing by the EPA and the CARB.

ROUSH Performance, a leader in performance engineering excellence, has announced that both the 775 horsepower and 750 horsepower 2021 Stage 3 Mustang is now certified as a 50-state emissions compliant pre-titled vehicle. ROUSH Performance prides itself as a fully compliant new vehicle manufacturer, obtaining full certifications for all 50 states, ensuring that the vehicle emissions systems will perform to OEM standards for tailpipe, evaporative and diagnostics for a minimum of 150,000 miles.

The certification process must be completed each year by vehicle manufacturers that wish to sell in every state. The two-part approval process starts with obtaining a certificate of conformity from the Environmental Protection Agency, followed by obtaining an Executive Order from the California Air Resources Board, allowing a manufacturer to sell its vehicles in all 50 states. This certification is legally required to sell new vehicles with emissions-related modifications and ensures that customers who purchase ROUSH Performance vehicles receive all the consumer protections of any other OEM vehicle. This is distinct from aftermarket emissions components, which cannot legally be installed on vehicles before sale, and which may impact the customer’s ability to receive their full new vehicle warranties and legal protections.  

Installing or selling new vehicles that have been modified without obtaining the required certifications can result in severe fines for the parts manufacturers and the selling dealers of up to $45,268 per vehicle. Compliant vehicles can be readily identified as they will have an underhood vehicle emissions control information (VECI) label from the certifying manufacturer; will have updated fuel economy labeling showing the performance of the modified vehicle; and will include updated owner’s manual documenting the emissions warranties.

“It’s not as simple as adding a supercharger and getting an emissions test,” said Kevin McLoughlin, director of product strategy, ROUSH Performance. “We have to change so many of the mechanical and related components that ROUSH Performance becomes the manufacturer in the eyes of the law. We’re proud to be able to offer a fully compliant, 775-horsepower muscle car that you can pick up off a dealer lot, with a warranty.”

ROUSH Performance’s 50-state emissions compliance 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. In addition, the 2021 Stage 3 Mustang features ROUSH Performance’s three-year, 36,000-mile body warranty and a five-year, 60,000-mile powertrain warranty. The 2021 ROUSH Stage 3 Mustang starts at $24,995 above base vehicle pricing.
