None of the power but just the looks. Yeah it sucks we don't get the old skool WRXs here, since they look so much better than the one we do get.;) But if you come here for the Detroit Auto Show in January... I might see you around. :D

whats the trims under the rear bumper?
are they the same as the ones we get modded to fit?

i always thought the usa rear bumper was just a early classic bumper without the trims (like a type RA model)

The underbody kit is actually the GC8 Orciari kit which includes the lip, sideskirts and rear spats. The rear spats do not fit the USDM bumper without tweaking it. It is similar to the STi rear spats but it has a bit of a curve to them rather than being smooth.
