This particular 1997 Chevy Camaro may or may not be a 50 state (California) emissions certified vehicle, however even if it is not, that will not stop it from being able to be registered in California.
The rule is any used vehicle which is equipped with the necessary Federal Emission Components (if it is a 49-state emissions certified vehicle) is eligible for California registration as long as the vehicle's exhaust emissions fall within California's limits (1999 & older vehicles only) and the vehicle's emission system has not been tampered with. This exemption does not apply to new vehicles. The emissions certification of this Chevy Camaro can be found by checking the Underhood Emission Label.
