Check on Nasioc there are a few up for sale with the elbow included. You couldn't just get an elbow and bolt it to your BPV since it has the wrong flange. By the way the sti's and wrx's have different part #'s but they are identical. Don't pay an arm and a leg for an sti if you can get a wrx one for cheap. I picked one up for $25 shipped just last week, I am pretty sure there is another one up now.
