Is there a difference in rear aprons?

Hello dear community, yesterday I parked my rear apron on a stone in too frosty weather and damaged it. Now I actually have a V10 TDI. However, there are so “pseudo exhaust pipes” from the W12 mounted on me. The previous owner had them built on VW, so I don’t know anything about it. Don’t know if you know them, they are just end tube flaps. Now I have a few questions so that I can talk something about before the reperture: Now the apron from the W12, is that different from the V8? Does it make a difference whether I drive a long version, or are the rear aprons the same?
