I have a ticking noise coming from the right hand side. I asked a friend he said it sounds like an exhaust leaks from one of the joints. I took off all the panels and tightened the clamp about 3-4 turns it got a little better but can still hear it. Anyone had this problem? I'm going to order the the exhaust bushings and see if that helps. Only have 6600 miles the book says they should be replaced at 12000 ?
