If you are near Orange County I have a good "test only" place where I take my LP640 and MBZs, and he does a lot of exotics. He is very knowledgeable and may be able to talk with you about exactly what you need in accordance with the CA books for visual and at the pipes even before you go in for an actual test. One of the few smog guys I have found that will actually talk with you about your car.
