This is normal with any car. After the exhaust system runs at 300+ degrees for a steady period of time, and the car is shut off, and immediatly the system begins to cool to the outside temperature. The metals contracting to such a low temperature at such a lower rate, will cause this pinging sound like clockwork.
racingtiger, this could be something as easy as using to thin of oil during your last oil change, low oil, or something as serious as a valve tapping. Do you remember the viscosity of the oil during your last change?
