The M Performance Power Kit ensures an optimised engine and exhaust system sound. Exhaust bubbling is enabled in "Sport" mode. As a result, the car sounds like 'performance'.
I’ll see if I hear a difference next time I take bae out. |
Usually cold start will be a bit louder just with mppk. burbling is more pronounced in 1st and 2nd gear around 1700-2000 rpm. Try driving in sports/shifter to left around 25-30 with windows down in 3rd gear and then drop it to 2nd. While keeping it in 2nd give it a sharp press of acceleration just to get rpms up and let go
