Default Rattling noise in the back

Guys
Trying to track down a rattling noise - like sheet metal tapping. Wanted to see who's encountered it or similar and had a fix for it.

So this is how I get the "noise". If I'm doing about 60kms (37mph) and in 3rd or 4th - revs are about 2500 to 3000 rpm - If i push he throttle down about 2/3rds I get the rattle noise.
Very "tinny" sound - like sheet metal rattling.
If the car is parked and I tap on the corners of the rear bumpers - around where the mufflers are located - on both sides - I get some sort of rattle.

Anyone had this and had a fix for it?

I figure I'm going to have to take the rear bumper off and drive around for a while to see if that's where the problem is coming from.

Thanks in advance.

Ken

I would check the muffler and catalytic converter heat shields as well as the rear fender braces (called "support tubes" in the parts diagrams) to see if they are loose.

Also check to make sure it's not one of the little fender liner screws. Sometimes the rubber backing falls off and it pings against the inside of the fender. Noticed this in the rear in two of my 993s and was able to fix by putting a little felt adhesive thing under it.

I get this noise! Drives me nuts. I get it now over bigger bumps too.

If I hit the fender with the flat of my hand just above the rear wheel on each side I can recreate the noise but not locate it.

It is all I can hear now when I drive.

Man - it's the worst feeling.
Thanks chaps - I will get the car up on jacks on the weekend and look at those places you all mentioned.
