won't pass smog with headers - the catalytic converters are integrated into the factory exhaust manifolds... all aftermarket exhaust headers that I know of eliminate the factory catalytic converters...
you could potentially get O2 simulators for the rear O2 sensors which would trick the computer into thinking the cats are still there, but, if anyone looked under the hood, it'd be pretty obvious they were missing...

Headers won't pass the visual and the sniff test portion. I can't give you a definite answer because I only had to do a smog check once when I was stationed in San Diego and all I had was a catback exhaust.
