Unhappy Advice needed 2016 M6 Competition Edition

Hi everyone, i become lucky owner of 2016 M6 Competition Edition(BMW Certified until 2021), right after i picked up car same evening had a problem with weird noise coming from rear of the car when i was parking it(noise attached)https://voca.ro/888kE5U63ZW
so i bring car back for service showed them video with this noise, and after 2 days i received call from SA and he explained me this noise coming from Exshaust system, and the one on car is aftermarket M performance titanium Acrapovic witch cost around $8000 and coming with 2 year warranty, and only 1 they found was located in Germany, and they trying to see if that will be covered under my warranty.
Any advice in this case please?(i believe originally those cars coming with OEM titanium exhaust system so i i think it should be covered since car is BMW Certified)

if its the M performance Akra, it should be covered regardless if it was bought with it stock or not.

Sounds like the exhaust flap(s) rattling. I have aftermarket akrapovic exhaust too, purchased used (2016) M6 & heard this nasty sound from exhaust. after lifting the car & examining the exhaust, I was able to disconnect the little ball joint(actuator) threaded arm (tightened it) & now I hear nothing but that beautiful exhaust note! if your exhaust looks like this, the area in red is where I noticed play (as compared to the other side with no play & no rattle). The arm just pops right off at the ball joint. I then adjusted the green area (outward in my case) untill I had no more rattle.

That is the actuator that opens and closes the valve. I wired mine open. I wasn't aware you can simply remove it, but if you remove or tightened it, it'll keep the valves closed longer.
