Rattle Sounds on 2004 Mazda MPV

When the car is cranked or when I accelerate, there is a rattling sound. I've been told it might be an exhaust leak, but I wanted to find out how much it would be to fix that.

Get it checked out by a Mazda specialist.
It could be a broken exhaust hanger if it makes noise when cranked, and a broken motor mount if it makes the noise when accelerating...
