    Default Catalytic Converter Question

    I have an 01 burb 1500 4wd. My service engine soon light came on. I had it checked and it seems that I need a new catalytic converter. I am looking into changing it to a direct fit but here's my question.

    The burb conforms to California Emission, ULEV and is OBDII compliant. I now live in AZ and when I called Magnaflow they are telling me that I need to get a CA legal cat since the PCM may not like what a 49 state legal cat would do. I understand that the PCM has CA specs on it but I cant understand why I can install a 49 state legal cat instead. On a side note, I called Summit and they wont even sell 49 state legal to me since my vehicle is conforms to CA. I told them that according to their site they cannot sell or ship to a CA address, I am in AZ.

    Any thoughts what I should do. There is atleast a $300 diff between a 49 state legal and the CA legal cat.

    Hope this makes sense to someone.

    When it comes to Ca. emissions the laws are real strict. I fought this battle a few years back.
    I had a Ca. emissions vehical and was living in Tx. when I was buying the replacement cat they wanted the VIN for the truck it was for, once they got the VIN they refused to sell me the kit I wanted so I had a friend with the same year truck buy the cat for me. I found out a few months later this was considered a violation of clean air standards and carried heavy fines for altering or modifying the exhaust system with unapproved parts. The vehicle was wrecked soon after so it doesnt matter anymore.
