  • Direct Fit Catalytic Converter: No Fabrication Needed, EPA Compliance

    MagnaFlow - Direct Fit Catalytic Converter: No Fabrication Needed, EPA Compliance (Part No. 27403)

    Description
    Keep the check engine light off with MagnaFlow HM Grade Federal/EPA Compliant Direct-Fit Catalytic Converter 27403. With features including free-flowing mandrel-bent tubing and highly corrosion resistant stainless steel construction, easily install this spun body converter yourself using the proper tools, no cutting or welding required. MagnaFlow's state-of-the-art metrology department uses the latest 3D scanning systems during research and development, so you can be confident that your new part will fit and function like the original equipment. By replicating the OE spun body design, the single laser fusion weld greatly reduces the possibility of a leak, and our compact, low-mass design also allows for greater thermal efficiency. Designed to fit the 1999-2004 Honda Odyssey, 1998-2002 Honda Accord, and more, this direct-fit catalytic converter also interchanges with OE parts 18160-P8F-A10 and 18160-P8F-305, among others. Avoid potential exhaust leaks by using the included gaskets to get a proper seal. This replacement part is designed to meet or exceed Federal emissions requirements set forth by the EPA, complying with legal standards for OBDII Federally registered vehicles with Federal/EPA Emission systems.
