Can I verify if it would pass a smog test as it is now? No. Only because I know the Cat is hollowed out and there's no testing facilities in Hawaii.
It was converted over to US spec exhaust, all that would be needed to get her just the same as all the other 500E's running around the mainland is replacing the Cat, once that's done it'll be the same running gear as all the rest.
It had her conversion done in CA, she passed everything up there to get her federalized, once she was here her Cat was hollowed out.
That's the best I can do.
