Received my DMV renewal notice couple weeks ago. In seemingly a "non-smog" my car was "selected" for "random" test at special STAR station. These are different from smog only centers since apparently they read the ecu to check if car has ever had any programming mods done. Of course, Im guilty. The tech also crawled under car to inspect actual cats. I failed that too. (downpipes) Not sure but it seems as they only accept the factory cats. Just thought about that, so I will go recheck with tech. Anyway, watchout for it. Im wondering if all modifiable cars being sent to STAR stations in cali. Anyone else have experience with this non sense?
