Stick with the BPV (by pass valve as a BOV (blow off valve) will mess up the air/fuel mixture since the WRX's MAF (mass air sensor) is before the turbo. It isn't worth the tuning headaches and would only really work properly if the MAF sensor is moved "after" the turbo/BOV. If you still want a BOV, The Hks unit is one of the more popular, but Tial, Blitz, Greddy, Turbo XS also make good units.
