Cars built from 2000 on carry a standardized onboard computer. We read it directly, so there's no tailpipe probe and no dynamometer.

Every passing smog check carries an $8.25 certificate fee set by the state. It is not optional. The only question is whether the shop quotes it to you up front.

Different test. Cars from 2000 on have a standard onboard computer we can read directly. 1996–1999 cars have to be run on a dynamometer with a probe in the tailpipe, which takes longer and uses more equipment.
