On the weekend I remember we were talking about this and someone (I think it was kevin) was saying that there is no cat in the uppipe in the 04 WRX. Today I checked my old uppipe, (which is conveniently sitting on my garage floor), and there definately IS a cat in there. (Either that or a gerbil got stuck in there).
Sorry franz, looks like you will be forking out the extra money after all
