I'm not in Calif... I often hear that "correctly" generally includes
the stock exhaust of the new engine, that's what I hear.
Just did a quick search and found this:

"Replacement Engines
Entire engines can be replacement parts. As with any other
replacement part, the engine must be identical to the original. If
the replacement block or engine is obtained without emissions
equipment, all the equipment from the original engine must be
installed on the replacement block.
If the engine is not identical to the original then it is not a
replacement part, instead it is considered an engine change.
Engine changes are a modification that must meet certain requirements
to be legal (please see "Engine Changes"). "

Engine Changes
Engine changes are legal as long as the following requirements are
met to ensure that the change does not increase pollution from the vehicle:
The engine must be the same year or newer than the vehicle.

The engine must be from the same type of vehicle (passenger car,
light-duty truck, heavy-duty truck, etc.) based on gross vehicle weight.

If the vehicle is a California certified vehicle then the engine must
also be a California certified engine.

All emissions control equipment must remain on the installed engine.

After an engine change, vehicles must first be inspected by a state
referee station. The vehicle will be inspected to ensure that all the
equipment required is in place, and vehicle will be emissions tested
subject to the specifications of the installed engine. " <<

That sound about right (it was dated 2007)? I'm not planning on
moving back to the Bay Area but I am curious about all this.
