Here is a first look at the Kelleners Sport aero kit and exhaust system for the F10 M5. The cosmetic parts include a carbon fiber front spoiler lip, carbon fiber mirror covers, sideskirts, black rear bumper diffuser with carbon fiber fin, and carbon fiber trunk spoiler. Black 20" Kelleners Hamburg wheels are fitted on the car.
For performance and sound, the Kelleners Sport full exhaust system with valve control has also been fitted. The valve system has been integrated in the rear silencer and can be opened and closed automatically, depending on the RPM and speed of the car. The valve starts in the closed mode at startup, but opens up at approximately 4000 RPM. An Export version (Sound+) is also available. The quad tips are stainless steel with 90mm diameters.
No word yet on any ECU software tuning, but you can bet on it coming.
