Yes, counting from head down. The factory bung after the first factory cat. You can’t mess with the factory ones before cats, as I understand.
Important, And you need to have the tuner turn off those same sensors after cats in the tune before you disconnect them and use one of those bungs for your wide band. Otherwise it writes an unerasable emission error code to the ecu. Or so I understand.
