I want to get a bung welded in for a wideband. Right now Im making 2 assumptions:
1. Wideband sensors use the same thread size as regular o2 sensors.
2. The bung should be before the main cat for increased accuracy (no precats- headers).
Am I correct? I also havent found any bungs that come with thread in plugs. Anyone know where to get some? Also, should I worry about the y-pipe coating after getting the bung welded on? TIA.
