Many of the touring bikes at one time or another will experience a squeaking coming from the rear of the bike when hitting some bumps.You'll also see that there is some play in the rubber mount where the support bracket (muffler) can move up and down a bit, this is normal.
The length of the support bracket when properly installed is about equal both in front and the rear of the support bracket where the rubber is as seen in the pics below. This also relates to the amount of the slip on muffler being adequately installed on to the head pipe enough to seal the slots in the muffler tip so there is no leakage.
Some silicone grease applied top and bottom on the bar that runs through the muffler support ( red arrows in the top pic) will usually take care of the noise.
If the squeaking problem persists after greasing them , it is usually dried out muffler support insulators and should be replaced then.
These isolators are necessary because the engine being rubber mounted moves a bit and if these isolators weren't installed, the pipes would fatigue and eventually break.
