The stock 04/05 STi scoop has a different footprint and will not fit, but you can either use the 02/03 (v7) STi scoop as Peaty pointed out, or use one of the knockoffs of the 04/05 look that were designed to fit the Subies with the same hood scoop footprint as ours (MRT comes to mind).
Sweet thanks! Thats just the look I'm going for, but maybe I would get a smaller scoop. I am searching for a scoop that I do not have to get painted, unless they whoever I buy it from does the painting there.
I think he went with a GT35 rotated setup IIRC. I think they guy lives in San Diego. I had a Seibon 04-05 style STi scoop with the 02-03 wrx footprint. Jake (dizizjake) has it on his car now and it looks sweet! It looked a little too out of place on my CGM XT but right at home on his JBP XT, heres a pic:
