Try checking the heat shields on the exhaust pipe up front under the car. Alot of times they will loosen up, and begin to rattle. You can ither remove them, or try to clamp them.
Hope this helps!

You problem is most likely just lifter noise. This is common with a lot of Ford engines with self adjusting lifters. Although lifter noise is bothersome it doesn't pose a serious problem. Unless your engine starts to miss or your gas mileage drops way off lifter noise is just an annoying problem.
I would recommend that you add some Sea Foam Engine Treatment($6-$8) to your oil. This is not an oil treatment it's more of an engine cleaner. If this works you'll need to add it every 2nd or 3rd oil change.
If this doesn't take care of the problem then depending on your engine you may have adjustable rockers that would allow you to remedy the problem. If not, your options are limited to living with it or replacing the lifters and possibly other valve train parts.

SOURCE: loud rattle noise started on
Sounds like the Cat could be bad. Get under the vehicle and hit the cat with your hand. If it rattles then you know what your problem is, if it doesnt rattle then start check the belts and tensioners
