[BMW550mike]

Greetings everyone, I am new to the community and have searched thoroughly for an exact answer to the question I have today about replacing my STOCK 2011 550i bumper (not m-sport) and converting it to the M5 rear bumper with the aggressive looking diffuser and real individualized quad exhausts. Now the questions I have are in regards to the fitment of a bumper like this on the car, what is required exhaust wise and what recommendations would you give to someone who still would like to maintain a relatively quiet exhaust but have the look. Any answers on a rough guesstimate in terms of cost would be appreciated as well. You will have to forgive me if this question has in fact been answered, I would just like to be certain if I am to do this that it works for my car for certain. I have attached photos of my current rear bumper below.

Thanks
