Kelleners Sport BMW M5 KS5-S

Even if the new BMW M5 is still quite rare, Kelleners Sport already offers a complete exhaust system with valve control for this new sports sedan.

Kelleners Sport has developed a valve system that has been integrated in the rear silencer. This allows it to be opened or closed automatically, depending on the rev and speed of the car. That means that the valve remains closed by a cold start in order to comply with the legal noise regulations. From a rev of approx. 4.000 rpm the valve opens and delivers a much more sonorous exhaust sound.

As completion of the offer the appropriate mid silencer is also available; as well as an export version (Sound +) on request.
