All Honda's have issues with heat shields. If there not real bad they can be tacked, clamped, or wired to stop the vibration. Worst case scenerio the heat shields fall most of the way off and have to be removed. Twice last week I had two Hondas dragging there Cat heat shields. The only thing holding them to the car was the wire harness for the O2 sensor!
Basically if it is making noise there is a resolution to the problem. You just need to find someone who wants to do it!
