I bought a "Federal" car that originated in Florida and ended up in SoCal. I have the complete history and it passed "smog" many times even though it doesn't have a CE light.
Another tip when you think you are ready for the test is to drive over in 1st gear @ 4000 RPM. That will hot up the cat converter and help your cause.
