I believe InCon had (yep, past tense) a smog legal kit, but they are out of business now. Maybe you can pick one up off of Ebay. I took wanted to turbo my car, but w/ no legal NEW kits, I decided to just supercharge it.
HPs kits are not smog legal. I already called them
They told me they can pass the sniffer part, but of course, not the visual.
