Re: rattling noise coming from jeep...
Take it to a good muffler shop and they will inspect the exhaust and tell you if there is something rubbing for example on mine it was the muffler rubbing against the back somewhere- they added a flange and fixed it. I also installed an intake in which a bolt came loose and the heat barrier was rattling-For that I just zipped tied and secured it so it wouldnt rattle. Also check your heat shields under jeep...
