Does my vehicle have EGR based on the exhaust information sticker under the hood? 200 1992

I am replacing the entire exhaust on my 92 wagon from header pipe back. Can I tell by the info sticker under the hood whether there is an EGR system in place or not?
Do I get the header pipe with an O2 sensor hole?
The sticker says “Exhaust Emission Control System: MPI, H02S, TWC
Thx

      google is your friend

      appears you do not have EGR but do have an O2 sensor.

        Thanks. That’s what I was thinking.. but the header pipes available for non EGR cars do not have an O2 sensor hole.

          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.
