Metallic rattle on the overrun?

Metallic rattle on the overrun?
Forged classic, it's running fine, but when you lift off, a metallic rattle can be heard, which sometimes seems to come from underneath, sometimes from under the bonnet. It immediately disappears when you touch the throttle again.
I've looked at the rear brakes and the turbo heat shield, but am now stuck for ideas.
Anyone?

Hi! mate, I've suffered a couple of these, first one was the cat heat shield, my new zorst sorted that one. The second was harder to find and in the end it turned out to be the heat shield on my up pipe. It had come away at one end the higher turbo flange. Removed and welded it and all has been quiet since. Hope you find it.

Did it do it all the time, or just on the overrun?
Just listened to yours, mine's nowt like that. Yours is more tapping, mine's metallic. I THINK it's the cover over the back box vibrating/rattling, very tinny.
I shall try stuffing it with rockwool when I get it back again, Mrs has it tomorrow.

I have a metallic rattle on the overrun, as well as if I drive in high gear at low speed (to instigate a vibration). My exhaust manifold heatshield is in bits, so I think its this.
