Trying to make my 93 smog legal, I have a pair of mini high flows for my Y, only issue is they are 2.5 in/out let, I have every reason to believe short of measuring that my off road Y is 3 inches. Is this .5 inch restriction going to cause an issue?

Should not hurt you that bad with stock cubes and stock heads. You will be ok. You will have to upgrade to at least 3" cats if you get heads/cam and or larger cubes.

Yea, your not flowing an insane amount. Your not going to see a noticable loss by any means.
