Rattling / Banging Engine Noise

Aloha again,

I realize this is probably answered somewhere and I did a quick search. In the past couple of weeks my rover has started making a rattling / banging noise. It's gotten worse and definitely is related to engine RPM. Sounds like metal on metal sort of slow rattling. Did a quick look underneath and could tell it seems to be coming from the bottom of engine/tranny area. Catalytic converters maybe? It's dark now so I couldn't get a great look. Otherwise, runs just fine. Just wondering if anyone had some quick ideas as I'm shipping it back to the mainland in less than a week. Minor or Major? Thoughts?

Thanks for the help. 94 D-90 with 3.9 l v8. 100k

Probably a rattling cat. Usually the flat cat goes bad first.

There is a heat shield under the exhaust manifold attached to the engine block that could be loose or have partly rusted. I had this problem in the past with symtoms similar to yours.
