My exhaust (MPE) developed a loud rattle recently that was especially noticeable upon startup. I immediately assumed there was a crack, but none were found. Took the car into the dealership last week and the exhaust tips were found to be the culprit. All four tips were replaced and the problem seems to be gone now.
