Noises under carriage

Well, I cranked up the old 97 Aerostar the other day and after the engine
caught, for 2-3 seconds I heard a rumbling noise underneath - hard to tell
but sounds like coming from the back half of the van. It doesn't do this
every time. Anyone ever had this happen? How would be the best way to pin
point the problem, since it's intermittent.

Thanks!

Fred

Suspect exhaust piping, do tug and wiggle test.. have a tendency to break
at flange between cat and muffler

And the whole exhaust system can drop to the pavement when it comes
apart there.

Many thanks. I've got my wiggle face on and heading outside to check.
