You could be talking about the M3 version.

Give us a minute i'll find a piccy/part number

EDIT: cant find part number for the M3 one on RealOEM.

There a couple of topics on here about it if you can find them in the search. I dont think it is carbon fibre but i'm pretty sure it is a single pressed/moulded sheet. Bit of a premium to pay though.

The M3 version is pictured above, part number 28.

[Chris]

Well in that case.

28 SOUND ABSORBER 1 51481979952 $135.04

And u'll probably want some of these:
29 EXPANDING RIVET ? 51481938725 $0.33

Dunno how many though.
