I just picked up an 08 550i and want to add quad exhaust. Does anybody know what the best approach is? I found this bumper on ebay but not sure if it will mount on my 550i M-Sport package, as i don't have a lot of experience in this area. (

I'm really hoping this can be done with a clean install look. What exhaust advice does everyone have.
Thanks in advance!
