Hi Max. Thanks for contacting us tonight. If the previous owner has drilled holes in the Catalytic Converter, then any error codes or diagnostic OBD-II codes would be irrelevant, as it’s an alteration to the OEM system. Based on the input you’ve offered, I think the best bet is to replace the cat - as the holes are most likely creating the pressure issues you’re experiencing. This would at least give you a base line to attempt to accurately diagnose your problems.
