MagnaFlow 447206 Catalytic Converter

California OBDII Catalytic Converter

MagnaFlow 447206 is a universal California Grade catalytic converter built for OBDII-equipped vehicles that need CARB-compliant emissions control. Its 2.50-inch inlet and outlet, stainless steel construction, and weld-on universal design make it a practical replacement for select applications that require cutting and welding during installation.

For drivers searching for a California OBDII catalytic converter for Ford E-350 Super Duty, Chevrolet Express 2500, or Nissan Frontier applications, this MagnaFlow unit is engineered to meet California Air Resources Board requirements for the listed vehicles.

• California Grade CARB-compliant design for listed applications
• Universal fit with 2.50-inch inlet and outlet diameters
• Stainless steel body and tube construction for corrosion resistance
• Ceramic substrate material
• Oval clam shell body with attached heat shield
• Weld-on inlet and outlet connections
• Designed for OBDII vehicles to help keep the check engine light off

MagnaFlow Universal California Line

The MagnaFlow California OBDII catalytic converter line is built for vehicles that must meet CARB emissions standards in California and other CARB-restricted states. Part number 447206 uses a universal layout to cover a wide range of listed fitments, while still requiring fabrication for proper placement and alignment. This makes it a strong option when you need a legal replacement catalytic converter for specific rear-position applications on trucks, vans, SUVs, and select Mercedes-Benz models.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Problems It Can Address

• Failed emissions inspection due to a worn catalytic converter
• Check engine light concerns related to catalyst efficiency
• Restricted exhaust flow from a deteriorated converter core
• Corrosion damage in the exhaust system
• Need for a CARB-compliant replacement on listed vehicles

Installation Notes

Installation requires cutting and welding. Verify inlet and outlet orientation, body dimensions, and vehicle-specific CARB Executive Order coverage before installation. Because this is a universal converter, proper fitment depends on correct fabrication and placement in the exhaust system. No oxygen sensor ports are provided, and mounting hardware is not included.

Quality Assurance

MagnaFlow 447206 is manufactured to meet or exceed California Air Resources Board requirements and has undergone additional testing for CARB guideline compliance on the listed vehicles. It is approved for legal use in California and other CARB-restricted states only where the fitment listing applies.
