Had the exact same thing with a snowmobile muffler. We were wondering why we saw a field mouse running around the truck box as we brought it home! We cooked the nest out with a acetylene torch before repainting it and putting it back.Mice had built a nest inside the expansion chamber on my dirt bike. It was packed so tight it wouldn't let the exhaust escape and wouldn't rev up. Luckily you could see a little exhaust coming out where the pipe fit to the engine. They had to have somehow jumped off the seat and down through the silencer to get inside the pipe. We managed to blow some of it out and put the pipe back on. Started the bike and when I revved it up shot a good portion of the nest out the exhaust. Very Bizarre.
