OOOOH a subject that i know a bit about. I have had 2 really annoying rattles in my car.
First one was a bracket in the mid section of the exhaust system that was not alligned correctly. Net result an annoying rattle
Second one whcih was much harder to find turned out to be a defective boot catch.
What i found really difficult was to pin point the rough area the rattle was coming from. After a while it drives you potty
