Im in the same boat your in right now for emissions testing. The conclusion i have come up with is this. My tuner said with an SCT tune you can turn off 1 parameter and keep the ecu ready for scanning. Once EGR is removed that will be turned off, and no check engine light. Now with the rear O2 sensor, there is a couple different options.
O2 cheater, which i heard work sometimes. Because you have a duratec you can use a spark plug non fouler and put the O2 sensor in there. Because i have a zetec i am going to use the way Focussport recommended when they released the race header. Take out the rear O2 sensor and plug it with a bolt/plug. Put the O2 sensor in a ziploc bag and ziptie it somewhere underneath the car. Either in the engine bay or underneath the car will work fine
All the second 02 sensor reads is emissions. Whether it has clean air or not. So if it has atmospheric air, it reads no problem, and then no check engine light. Keep the cat off, considering the government doesnt care what is coming out of the tail pipe, just if an idiot light is on in the dash.
Hopefully this helps
