Problem solved

After having straight pipes fitted yesterday, the whole exhaust system obviously has to be dropped down to be worked on. When it all put back in place everything must have been tightened up.

If the rattle was coming from the broken up silencers, they are now completely gone, and I got under the car and checked the thin pressed metal heat shields that surrounds the exhaust at the back, and there is absolutely no play anywhere in it.
