Hi. I got the one piece bumper on my A3 Sportback MY11. I really like the RS3 or Facelift S3 diffusers. But i know they won't fit my bumper. Have anyone seen a great aftermarket alternative? Or have anyone been in the same situation? i really don't want to swap the entire bumper, just the diffuser. Every replica i've seen from Ebay is for a 3 door, or the 8P3 or 8P2 bumper and sits in a lower valance. But my bumper is a one piece. My bumper is the same as shown in the picture.
