Link to a quick explanation of Cali exhaust laws.
To sum it up; slip-on mufflers are legal for use unless the muffler being replaced contained a catalyst. If the headpipes contain a catalyst they can not be altered. Starting in 2013 EPA noise regulations begin for all new motorcycles and exhaust systems.
