weird m tech bumper
 

i got my 2014 m sport 535 xdrive and i have this bumper. i never seen one like it on the street or bmw.
the only pic i found was this one from ebay. do all of the new ones come like that????

thanks

you have the correct bumper, its the diffuser that makes it different. You have an aftermarket rear diffuser, possibly the same diffuser found in that ebay link

its not aftermarket i actually found it on the bmw website. its basically an aerodynamics add on

how can it b aftermarket i got it on a new car

It's from the BMW m performance range for the 5 series.

Interesting diffuser
