BMW M4 F82 with Eisenmann Catback + Akrapovic Catless Downpipes – LOUD Sound

This is just a short clip where you can see/hear a BMW M4 F82 fitted with Eisenmann catback exhaust and Akrapovic catless downpipes revving multiple times, producing an incredible sound. This is probably the loudest M4 I have ever heard. What do you guys think of it?
