Or is the burble the result of engine being in sport mode? Very curious..
If i am not mistaken there are 2 set of flaps as you have the M performance exhaust. The stock car comes from the factory with flaps which open/close depending on the mode selection and are situated in front the end exhaust box. The m performance exhaust has a different end-box and additional flaps which sit behind the end-box and you can control from the Bluetooth controller and even see them operate if you look in the exhaust tips.
