F30 320i stock exhaust drone?
Hi fellas,
Lately Ive been experiencing drone with my 320i stock exhaust. It is most violent when the engine is cold, anywhere between 20-60km at 1K RPM. Even when warm, the drone still persists In 5th/6th at 1k RPM. It can get very very annoying at times. Just wondering If its normal at all - and If i should explain the issue to the stealer? No exhaust mods or damage - car built in JUN 2015. Thanks
