difficult to say, you need someone Expert in how the smog check works in California, i think they also Connect to obd and check for "things" our euro cars with euro calibration don t necessarily count for

in italy they only check exhaust gas with their sensor, so i regularly tune people also with aftermarket without cat Headers, and the stock oem front pipe installed and they pass it if they show up there with a warmed up car
but California is rinomated for stringent controls
