Its an actual JDM STi type II lip for the 01-02 forester STi overseas. Nabbed it off ebay for a somewhat ridiculous price.
Keyword search "Subaru SF5" and you will find goodies from time to time, but be warned, they are expensive. I see a front bumper with the lip attached and the wider opening for a FMIC on there for almost $1k at the moment... unpainted.
Japanparts will have it too, but again... $$$$.
