Maybe one of the fins on the exhaust turbine? but that doesnt explain why it goes away when then engine is warmed up.

Get an oven mit and see if it still has the same "abnormal" knock when grabbing the heatshield after all is warm.

Do you have any smoke out the tailpipe? If so, what color?

Well, metal expands when hot. Whatever might be loose when cold is now tight due to the expanded metal "filling" up the empty space that causes enough room for things to move/rattle or that are out of wack.
