Brutal Cold-Start & absolutely amazing pure exhaust SOUND footage the NEW! 503 hp & 770 Nm 2020 BMW M340i optimized by FF Retrofittings from Germany! Yes, this car really has some serious performance.

We haven’t experienced any other company that pumps out this magic 500 hp without any changes to the Turbos. The best thing about this setup. Everything fells rock solid and like BMW had developed it this way….and on top of that everything is 100% street legal in Germany:) What are your thoughts?
