We had a rather unique request for this N55 powered F15 X5. The customer wanted a little more growl from the exhaust but also wanted to be in control of the sound. The solution was an electric exhaust cutout. The cutout is installed in line with the factory exhaust system and a toggle switch is conveniently hidden in the cabin for the customer to access with ease. This modification definitely changes the sound of the vehicle and raises quite a few eyebrows.
Here is a little sound clip with the cutout fully opened:
