Went to trade in my FR for a Cupra today with an Aero kit. Got a query with the Aero on it. I was under the impression that all aero kits had the dual exit exhausts (one either side). This one has a regular Cupra oval exhaust fitted into the Aero rear bumper, it looked original juest never seen it before. Is this the way all pre K1 aero bumpers on Cupras are?
