If the smog tech doesn't notice (or care) that the EGR is missing.....
You should have a pre-test done to see where your at. Make sure they don't send the info into the state !!!
You don't want to go get tested 'blind', then be so far over that you become a "Gross Polluter".
With out the EGR (or plugged passages), the NOx will probably be too high. If your cat is working, and NOx is the only failure part of the test, and its only about 100 or so PPMs over the limit, you can retard the timing back to 5*, or 0* for the test. This will lower the NOx.
The CO% and HCs must already measure low.
This is why for smog test areas, I recommend leaving the EGR alone. If your engine is working properly, it won't hinder power. If you just must 'clean up the engine bay', then save all the parts to put back on for the test. If you just 'can't stand egr', then you can just pull the vacuum line on the valve and stick a golf tee in the hose.
