have you considerd the afterburner?? well if not then you should

have a look on scoobyworld or check out ebay

 

Id consider a knocklink and a remap for a full decat on a V5 STi (should also be an MY99 not a 98, otherwise it would be a V4), Sti's are a bit tempremental to full decats, they are more "on the line" in the map and not running 100 ron fuel also can cause det and destroy your engine.

Agree, get a knocklink at the same time, run it on bare minimum optimax and get the full scoobysport system with jap style round slash cut tail pipe.
