It's not about smog; it's about revenue.
Here's the crazy part - - The tailpipe analysis can pass with flying colors, but if there is anything under the hood that isn't approved by the California Air Resourses Board (CARB) then the car fails and a certificate cannot be issued, and you cannot register the vehicle.
BUT - - as long as the visual inspection shows no "non approved" parts, the station can issue a certificate of compliance, allowing you to register the vehicle EVEN IF THE TAILPIPE EMMISSIONS EXCEED THE LIMITS!. Your car can be worn out and belching pollutants, but as long as the OE equipment is all there, and the smog station can make any adjustments showing any improvement, you can "pass".
If it was truly about clean air, all they would do is the tailpipe test. It wouldn't matter whether you had performance equimpent under the hood or not. If it's running clean it would pass and if it isn't, it wouldn't. Gotta love the People's Republik of Kalifornia!
