I was driving one day and everytime I changed gear I was hearing a rattle from the rear of my car. so when I got home I decided to gt out and check it(after I turned it off). well the muffler swayed a bit just by pushing on it lightly. thinking that one of the hangers had broken I crawled underneath the rear end and checked it. no broken hangers or anything. but I did notice that there was only 2 hangers on the muffler(1 on each end)and none on the actual tailpipe, which I think is rather long for a tailpipe, and that the 2 existing hangers looked a little weak in the gills. well the rubber hangers are being pulled by our heavy az muffler, not to mention that they are the stock muffler hangers from every other protege. so all in all I think we need upgraded hangers for our exhaust on the MP3.
