Exhaust Question
I have noticed that the drivers side exhaust pipe is black with soot and the passenger side is clean looking. Are both pipes active or is the passenger side just for show?

The passenger side has an electric operated flap valve. If you select sport mode you will hear the exhaust note changes. Perhaps you are not getting to use the car as much at the moment on the faster roads?

It would open the flap to allow the extra gasses escape when you are driving hard. Not sure if it is at a certain revs or just based on the sport button though.
