Not sure about the certified inspection. Maybe that just means a regular inspection from jiffy lube or dedicated auto state inspection place.
As far as smog, we don't have that. If you're in urban areas, they do an obd scan to test for readiness. If you're stage 2, you won't pass afaik. You can fail 1 readiness state and still pass.
If you have obd11 or obd reader with Torque, you can scan for readiness before hand to see if you'll pass.
