Description from video:
"During the RACE1000 in Germany yesterday I have filmed this unique BMW 'M2' Convertible (based on a M235i) fitted with Akrapovic Exhaust. BMW will not make the M2 Convertible, so thats why Kotte Performance customized it and is tuned to 550HP! You will hear some loud revs and accelerations during the 1/2 Mile Acceleration! I hope you will enjoy the video"
