Here are the things that the ref will look for to meet Carb approval.
Fuel system
Headers
Catalytic converters
Intake
Actual emissions test.

Fuel System:
Does it have a working and proper EVAP/Purge/Canister/Recirc.VS.Returnless fuel that meets the emissions standards of the body of the car or the engine.

Headers:
Are they OEM or C.A.R.B. approved

Catalytic converters:
Are they OEM or C.A.R.B. approved for that engine family

Intake
Does the intake have all the proper vacuum/evap that meets OEM standards.
Does it have the factory throttle body for that vehicle class (Can't put a truck throttle body on a sedan)
Does it have OEM or C.A.R.B. approved intake manifold

Emissions test
Does it actually pass a smog check.
