My problem is a rattle and not the squeak. There was a similiar, but louder rattle comming from the same side last year, back then it was due to the baffle being loose. I repaired that problem over the winter. This new rattle is not as bad, but it still takes away from the solid tone of the muffler. My dealer suggested I put some oil on the rubber mounting. I tried using WD-40 and it works for a while, but after riding for an hour or so, the rattle returns, perhaps a heavier weight oil is needed or some other sort of lubricant that will not burn away under the heat of the exhaust. If that does not bring a permanant solution, I am going to try the aftermarket mounts suggested above.
