Direct-Fit CARB Catalytic Converter

MagnaFlow catalytic converter 447273 is a direct-fit replacement built for specific GMC Savana applications. It is engineered for bolt-on installation with no cutting or welding required, and it is CARB compliant for legal use in California and other CARB-restricted states on the listed vehicles.

Key Features

  • Direct-fit design for specific exhaust applications
  • Stainless steel construction for corrosion resistance
  • Mandrel-bent tubing to reduce flow restriction
  • Ceramic substrate material
  • Pre- and post-converter oxygen sensor locations
  • Mounting hardware, gaskets, clamps, and hangers included

Detailed Description

MagnaFlow 447273 is a California Grade catalytic converter designed to match original equipment fit and function using 3D scanning in the development process. The stainless steel body and tubing help resist corrosion, while the mandrel-bent layout supports freer exhaust flow. This part is built for 2003-2005 GMC Savana 2500 and 2003-2005 GMC Savana 3500 right-side applications, with CARB Executive Order D-193-103 coverage noted in the fitment data. If you are replacing a worn converter on a GMC Savana 2500 or GMC Savana 3500, this direct-fit unit is made for a straightforward service replacement.

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

What It Is Used For

  • Replacing a failed catalytic converter that triggers a check engine light
  • Restoring exhaust aftertreatment performance on a CARB-listed application
  • Addressing exhaust leaks at the converter connection points
  • Correcting emissions-related fault codes tied to converter efficiency
  • Replacing corroded factory exhaust components with a direct-fit unit

Installation Notes and Tips

Install with the proper tools and follow the vehicle-specific service procedure. The bolt-on inlet and outlet design eliminates the need for cutting or welding, and the included gaskets and hardware help reduce the chance of a leaking seal. Verify oxygen sensor routing and confirm the listed fitment before installation on the GMC Savana 2500 or GMC Savana 3500.

Quality Assurance

MagnaFlow designs this converter to meet or exceed California Air Resources Board requirements and subjects it to additional CARB compliance testing for the listed vehicles. The part is developed with 3D scanning to support OE-style fit and function.
