Contrary to popular belief, muffler bearings do exist, just ask your local dodge stealth or mitsubisi gt3000 owner. Although a popular prank to pull on the not so automotive savy muffler bearings are located inside the muffler, in order to operate a flap which opens and closes depending on the exhaust flow directing flow back into the turbo. Due to inconvienience (carbon/other buildup often jammed the bearings causing noise and poor performance) the bearings are only found on older models.
Hey go into the garage and grab the blinker fluid and spare muffler bearings!
