"Smog Check Inspectors must check that all required catalytic converters (CATs) are present
and appear to be properly installed. This includes making sure there are the correct number
of CATs, that they are installed in the original location(s), and that they have no tampers or
defects. A change in the number of converters is only acceptable when it is allowed for by
the EO exemption."
>>>>"For older CATs without an EO label, use the general procedure described in the first
paragraph above. "
You need to find out when they were installed first. If installed before 2009, then do as above, if after 2009, then fail.
If it has the appropriate pre-2009 markings for the application, I pass it and make a written note on the bottom of the VIR. I do not generally require proof of installation date, because that would be a ridiculous joke in this neighborhood.
