Ok chaps, got the part from Japan this morning! Took me 5 mins to fit, looks superb and best of all I didnt have to buy an autodelta one!
The email address to order is:
flatout@f6.dion.ne.jp
The part is:
FLATOUT¡ÃSTORE¡ÃGTA¡¡Line¡¡Alfa¡¡Romeo¡¡147GTA/156GTA¡¡¥«¡¼¥Ü¥ó¥±¥×¥é¡¼¡¡¥µ¥¯¥·¥ç¥ó¥Ñ¥¤¥×
(japanese site)
Same for both 156gta and 147gta.
Cant really notice the sound of it too much as I've recently fitted a csc backbox. As for more power, well I doubt it. But it certainly looks good in there and de-clutters the engine bay so a tart's accessory more than anything else!

Quality of the part is first class with a nice 'GTAline' label under the clear coating.
Btw, customs didn't get their grubby fingers on it. Hope you are lucky too.
Flatout only accept visa card as payment and you will have to submit all your card details in the email when they request it. So you have to trust them. I haven't seen any bills for strip joints in downtown Tokyo yet
