      Description

      High-Performance Emissions Control. The Flowmaster 225 Series Enhanced Duty Catalytic Converter; 2.50-inch Inlet/2.50-Inch Outlet; 49-State Legal provides effective emission reduction to comply with federal EPA standards. Designed as a universal replacement part, it improves exhaust flow while minimizing Malfunction Indicator Lamp (MIL) triggers, supporting vehicle emissions system health and performance.

      Construction and Appearance. This catalytic converter features a robust stainless steel outer shell with a natural finish for corrosion resistance and durability. The internal ceramic substrate and precise precious metal loading are engineered to optimize catalytic efficiency. The oval clam shell body shape includes a heat shield for added protection and durability.

      Installation. Installation requires welding and/or fabrication and is recommended to be performed by qualified technicians. No drilling or additional complex modifications are typically necessary, but professional installation ensures proper fit and function.

      Warranty. The converter offers a 25,000-mile emissions warranty along with a 5-year or 50,000-mile warranty on the exterior case.

      Application. This catalytic converter fits a wide range of vehicles as a universal replacement and requires some adaptation during installation. It is not CARB-certified and is therefore not legal for sale or use in California or states that adopt California emissions standards.
