      Comments about MagnaFlow Direct Fit Catalytic Converter, Stainless Steel:

      This product is advertised to fit a 2003 Mazda Miata, however it did not have the port for the O2 sensor or the mounts to hold it to the undercarriage as on the factory installed converter. It would have required extensive modification (cutting and welding) to fit the model it describes as being " direct fit."

          No, you would need a second converter to complete the exhaust system in your 2002 Mazda Miata.

      • Q:

        After market catalytic converters are about 20% the cost of
        OEM ones. Several repair garages don't want to use non-OEM catalytic converters because they may not work properly, resulting in the check engine light coming back on later. What does Magnaflow have to say about the emission specs of their converter vs. OEM? While the part may be an exact fit as far as hooking up, the more important question has to do with actual performance with the car's computer. Thanks.

          This MagnaFlow Direct Fit Catalytic Converter, Stainless Steel with part# 23771 is designed for easy bolt-on installation for the professional installer. Welding, cutting, and tube-bending equipment are not required. It features a ribbed body that minimizes expansion and distortion when the converters heat up. The ribs form a channel that protects the cushioning mat from direct exposure to exhaust gases, and they hold the ceramic catalyst in proper alignment. These converters use a monolithic honeycomb catalyst. The ceramic coating is designed for maximum flow and surface area, and the coating method is strictly controlled to maintain exact specifications. An improper coating could result in flow restrictions or an emissions test failure. These converters are designed to exact OE specifications and are available for the most popular vehicle makes and models. In order to check the exact fit application, please provide the year, make, model and engine size of the vehicle.
