not sure if this question was answered or not,, but here goes.. a friend has a mugen steering wheel, and he wants to take off his oem steering wheel and put the mugy on. he lives in california. and it is not a track car. the question is, is it legal to drive without the airbag. does he have to put everything back to oem when he does a smog check? (not sure if the smog guys have a check list that they have to check off)

and i know the usual answers "well if the cop doesnt pull you over then your fine" or well just dont get into an accident"

whats the legality of it coming with air, and then taking the air out? legal or not?

thanks for the help
