Dynamic Parts Prices

Hi , new here and been reading though thread.Although there are loads of prices for the new parts it would def be cheaper to get a second hand one a repaint or add to.Saying that I take it the Dynamic full bumper will fit the prestige with a bit of fiddling with the exhaust and the extra trim bits ?

Is the exhaust change just the back box?

Are all the screws and fixings interchangable?
