Why is that? I find it pretty amazing, actually. Not questioning you as you'd know what they put it through when running the smog check, but why would CA exempt any production car from a major auto maker? My '05 Limited Roadster was smogged a few months back and they put it on the dyno. Passed with flying colors, but then again the powertrain is stock other than a Magnaflow cat-back exhaust.

On a side note, my '04 PT Cruiser Turbo has had some work done to it, including the Mopar Stage 1 ECU swap and a set of non-CARB approved hard pipes for the turbo plumbing. I go to a place that will look the other way - three other shops popped the hood, looked at the pipes, and said they'd wouldn't test the car because they'd have to fail it based on them being "illegal, non-CARB approved". Funny thing is, when the sniffer is jammed up the tail pipe and the car is run on the dyno, it blows so clean that, in the words of the technician, "you couldn't kill yourself in your garage with this car it's so clean!".

Yep, that's CA for you.
