there shud be 2 exhaust studs holding the exhaust to the bike. having the exhaust can disconnected does allow side movement as frames can differ altho it can normally only be moved if the bottom studs are loose, if they are tight and the exhaust is tight to the subframe then dont worry about it.

if the exaust studs are done up tight but theres still movement then you prolly need a new exhaust gasket
