The person who had the bike before most probably had an aftermarket can and link pipe fited, when he sold the bike on he would have put the original can back on.
I have no exup cables on my FZ1 and just about everyone else with an aftermarket can will have none fited either, the exup on the FZ1 is just for noise and emmisions and does not effect power unlike the FZS1000 Fazer where the exup valve does affect low down power.
Saying all that there are some others who say it is does affect power but if I were you I would not worry about it, I have never heard anyone say they have noticed any difference in performance when the exup is disconnected or disabled.
