So I decided to perform the Oem. exhaust mod . I replaced the 2 big perforated pipes by 2 full stainless steel pipes .
It was an experiment for me and I thought : If I fail , or don't like how it sounds like , I just buy a new BMW Oem. exhaust.
BUT !
I was was blown away by the sound . It sounds fantastic , and with zero drone .
Today I still love my Oem exhaust mod . It wakes the ///M S65 V8 really up !
During the cold start cycle It's loud ,It can be quiet when you drive normal . But when you step on it , It's like a race machine ! The sound quality always remains great and sounds really refined !
My friend , for further questions you can always PM me .. 
Video shows the DIY of the mod

Not my car but nearly the same set up. I have a Tubi Exhaust with X-Pipe so mine goes a bit higher on the top end and lower on the low end.
