I have a set of Rear OEM mud flaps for sale that I'd never got around to putting on my car and probably too lazy to do so at this point. It retails for about $120 at the dealership. It fits 03 - 06 Cayennes, and the part number is 955 044 800 13. I do have pictures, but shoot me an email or pm. It's brand new in box with all hardware included.
