I got one response out of 4 e-mails total I sent, and it did not say anything about a problem with the catalytic converters, as a matter of fact it said that the parts I had ordered should have been here already and that the situation would be checked on. I haven't recieved a response on what the situation is. I am not expecting one either, considering its been 6 days since I replied and my last e-mail wasn't answered until 7 days later.
