Hi,
I noticed that the car changes its exhaust sound when I switch from comfort mode to sport mode (no burble to has burble). I thought the reason for the burble is those flaps I have in MPE, but when I open the flaps (track mode on MPE) the sound gets even louder, does this mean there are two layers of flaps? Or is the burble the result of engine being in sport mode? Very curious..
