Ok Heres one for the real experts.... I have my O2 exhaust sensors disabled, and would like to remove them entirely from the exhaust header pipes. Can anyone give me an idea what size bolt i should use to close up the sensor holes? Dimensions and thread type and possibly where i can buy two? Do they need to be copper or any special material?
