I highly doubt that anyone makes a urethane replica of the stock bumper. There is a HUGE upfront investment in making urethane bumpers so an aftermarket company would likely not be able to make one more cheaply than BMW. So basically this is not something that you have to worry about.
That said, there should be a BMW sticker with a part #.
