I have this rattle that I hear when coming to a stop. It sounds like when a heat shield is loose or something to that effect. A really thin metal-like rattle. I've checked the heat shield over the turbo to see if that was loose from doing the wastegate turns, but that is tight and secure. I can mostly hear it from the passenger size and it's more pronounced when stopping next to a car where the sound bounces of the other car or retaining walls. Exhaust bracket is gone too. It's embarrasing stopping next to cars with this noise. Anyone here had this rattle before?
