Recently my exhaust fell off so I ended up replacing the bobbins.
From the forum posts it seems this is a fairly common operation.
I had a hell of a time with it though. Especially taking the nut off the top end where it mounts to the exhaust. I could turn the nut just quarter turn at a time because of the surrounding brackets. And often instead of the nut turning on the threaded bolt, the nut and bolt would turn together as it was no longer gripping inside the rubber block. My only solution was to dig away at the rubber block until I was at the metal insides and could grip it with pliers so it wouldn't spin when I was turning the nut. Exhausting though. Surely there must be an easier way.
