I'm guessing they are referring to the flange gasket between the header pipe(s) and the cylinder. Sounds like you ought to remove the exhaust and inspect (everything). Then reinstall and tighten up from the front working toward the back end.
Is the header pipe loose, or the muffler? Which part wiggles the most? There are only a few attachment points, so it shouldn't be hard to debug it. Are the springs holding the muffler still tightly stretched?
