I'm affraid you'll have to dig into manuals a bit and try to find out what are the basic concepts of export and why is it used for.

Unless your database is a total mess (meaning that any user appart from SYS has any object created in the system tablespace), nothing from the system tablespace is exported ever, no matter what kind of export you take. Remember that objects owned by SYS are never exported!
