I bought a 4 into 1 header off of eBay and though it appears to be a quality product, it only has one O2 bung in it located just behind the collector. I'm thinking it's
designed for OBD1 but the motor is OBD0 so I need the second O2 sensor. My question is how where should I put the second sensor? My initial thought was to plug the bung that it came with and put in two new bungs, one in the #1 pipe and on in #4, will this work? There's no non-ghetto way of putting a bung in so that it measures two cylinders at once due to the design of the header. I"m not willing to swap to OBD1 (not just yet anyway) and I"m not buying a different header either. Anyone's thoughts?
