Tried the search function to no avail. Has anyone had problems with a rattling noise from their exhaust system. It does not make it all the time only when you are accelerating not WOT. Seems to be coming from the passenger side. I have had it to the muffler shop and everything it tight. It is driving me crazy. Thinking it is a heat shield and somewhere from the manifold along it is touching. Any help is greatly appreciated.
