You just have to get past the thought that someone else farted in it first.
There's lots of youtube videos of WRX drivelines going crunch when the hammer is dropped, not so much with the STi.
Sure, it's got more power, but it also has a bigger radiator, bigger brakes, the center diff, the IC water spray...lots better than saving money on a WRX and spending the difference in two or three mods.
I _like_ it that way.
