Anyone know of a reverse hood scoop for MY04 WRX/STi's?

If someone could point me in the right direction that would rock!

seibon's cf hoods come with one, i think they sell them by themselves, but i don't know who carries their stuff.

Don't see reverse hood scoops on their site.

Its not listed as an individual item, but it does come with their cw2 hood:
