It wasn't such a simple question after all. While most of us know whether or not our cars have EGR (California), no one has yet explained to me why an oxygen sensor bung would need to be in an EGR car's downpipe, given the oxygen sensor is located in the catalytic convertor. This confusion exists in all the suppliers' catalogs.

Two explanations come to mind: One, the EGR pipe has a bung for a exhaust gas temperature sensor mistakenly identified by parts houses as an oxygen sensor bung, or two, a change in EGR made mid-production relocates the oxygen sensor, or precludes the spin-flange type of connection to the cat. I think I could know better if I had any experience with the 50-state California variety, but I do not.
