I am crazy about the one-off F82 BMW M4 and the sports car seems to impress me every time it popps up on the web, showing off with an extraordinary aftermarket body style. But this time, things have changed a little bit, as the famous M4 couldn’t get away without any mods under the hood.

The F82 BMW M4 is showcased in this video while revving its engine, thanks to the installation of the Akrapovic`s exhaust system, the entire upgrade program being carried out by the aftermarket specialists from the famous German tuner Hamann.

And guess what, thanks to the Akrapovic exhaust system, the F82 BMW M4 is now reaching a good 517 horsepower and impressive 700 Nm of torque, as opposed to the stock 425 horsepower and 550 Nm of torque.

Apart from the power boost, the Hamann tuner have also carried out some mods at the body style, the model receiving more aggressive body parts. As a reminder, the F82 BMW M4 was put on the market last year, coming packed with the already famous 3.0-liter inline six-cylinder turbocharged engine, hooked to the high-performance M-DCT transmission, and making the sports car reach 100 km/h in just 3.6 seconds.
