I believe it's been said that that was just a generic image they had; not representative of the actual catback. If you compare images of the exhaust (well, the chassis) there's not really a practical way for that catback to be installed on the car. My point - that image was generic and we'll be getting true dual exhuast with an X-pipe; that's at least what I've personally put together. Everything up to now points to that, anyways...
