Yes, but if the anal rententive smog tech sees the nitrous solenoid or supply lines, he'd probably fail ya right there. Furthermore, get stopped by the police with the system connected, and you'll have lots to talk about with the officer. h:

Hence my suggestion of mild-ish cams and internals. Paired with CARB certified parts externally, the liklihood of failing the visual part of the CA smog inspection is drastically reduced.
