Check engine light continues to come on says diagnostic says that Cat is bad and triggering the second sensor.



It has less than 5k on it, Toyota says its the wrong cat, my Toyota Tech says I need to replace it with a OEM or it will continue to trip the engine light.



I spoke to Magnaflow and they told me that its the correct cat for my 2000 4Runner. Told me to get a Emissions test and call them but they believe its something else.

Suggestions? Thoughts?

For the money and time I have already spent, I should have just bought the OEM Cat!
