I use my M5 for driving with my business colleagues and family and so far no probblem with the sound.

Great point.

I have the akra evo system on my M3 and you don't notice it when cruising on the highway or in the city until you get on it. The only times that time I notice it being really loud is during start up in my garage as it sets off the same Porsche Cayenne alarm every morning. Also, when I am using the bluetooth phone people sometimes ask "is that you car?" But most males will comment that it is awesome after you tell them that it is the car.
