Hamann BMW M4 with Akrapovic Exhaust Burnout, Revs, Accelerations & LOUD Sounds!

During Top Marques Monaco, I have filmed this grey BMW M4 F82 tuned by Hamann and fitted with an extremely loud Akrapovic exhaust system. Video includes the car starting up the twin turbo 3.0 litre inline 6 engine, revving and accelerating multiple times, producing an amazing sound!
