I can see what Stilov is saying. IF and only IF that little pipe connected to the external wastegate is actually INSIDE the stock hole in the turbine housing, THEN yes that wastegate setup would work. IF it is flush with the downpipe and not sealed to the hoel, then yes, it's doing nothing.
i.e. you CAN remove the sotck flapper, inserta tube into the wastegate hole in turbine housing and connect an aftermarket external wastegate to it. This MAY be what they did here, but until you reve that plate and see, you don't know.
