My car has a vibration noise which sounds all the world like a loose exhaust system. In fact, I initially thought that was the problem, but investigation and vigorous shaking seem to indicate otherwise. All exhaust system mountings are secure.
The noise occurs upon starting from a stop...it lasts only about 3 to 5 seconds and is gone. It also occurs when slowing down to a stop, also about 3 to 5 seconds.
One thought I have had was, "Can the interior of the muffler disintegrate and cause such a noise?"
Not much information,I know, but any leads would be appreciated.
Thanks in advance.
