This Sapphire Black 6SPD M5 came to us for a stealthy look and a not so stealthy sound. The first item on the installation list was a full Eisenmann sport exhaust system. Wanting to stand our from the crowd, the owner of this F10 opted for a black thermal coating on the mufflers along with quad 90mm slash-cut tips. Just like the OEM exhaust system Eisenmann's sport exhaust is equipped with Valvetronic technology, which modulates the volume of the exhaust note. Combined with the ExhaustMeister controller, the driver is able to simply push a button to instantly open or close the valves on the fly (watch the video below to hear it in action). Along with the exhaust, we also installed a UUC short shift kit for faster, more precise shifting of the manual transmission. Last but not least we installed IND's painted cosmetic package to eliminate the OEM chrome trim and front reflectors, while adding some additional ///M flair to the car.
