My truck passed CA emissions twice. Including the visual inspection. Just make sure you tell them your stock components failed, and thats why you aren't running a stock system. It is only illegal to replace functional equipment in CA.

Remind yourself that it's one high school drop out to get by for your "final exam" with the emissions test. If you pass the sniffer exam, there's not much motivation to keep you waiting.
I always paid the $40 to do a dry run at any other emission place, to make sure my sniffer test would pass when it counted.
I was only visually checked once.. and I think it was because how loud the 5.0 purred during the sniffer test....
