Then afterward it would be reverted back to it's modified form. They used a smog shop that was familiar with 930's since the rolling test specified the RPM range and speed but an early 930 with a 4 speed transmission could not do that so we always got a waiver and it passed.
There is a small bit of info on the CARB site that mentions the highway tests and road side tests are mandatory, no choice in the matter it appears?

Nope, they are not mandatory. What is mandatory is that the CARB is to perform the road side checks to collect data.
Verbatim from the website: "
Participation in the survey is voluntary. There are no consequences to consumers, regardless of their vehicle's emission control equipment or its emission levels. At the conclusion of the inspection, the participants receive a Vehicle Inspection Report (VIR) detailing the results of the test."
