OK, after hours and hours of searching for an e39 m5 rear bumper for sale (other than the 600$ oem one) I found nothing. Dont tell me to go check google, because I did check google, about 10 pages of their shopping section, and everyone that I clicked on that has a picture of an m5 bumper was fake. I would email to confirm the actual diffuser cut and it was for only one sided exhaust systems i.e. NOT FOR AN M%
So does anyone know where I can get an actual dual cut diffuser along with the bumper and not have to buy this crap and then spend an extra 100$ just for the diffuser? this is what my luck brought apon me...
I came upon nothing but this, over and over again:

And believe me, this is my last resort, wasting a thread dedicated to a rear bumper
