Would flashing the car make the exhaust more noticable louder when starting up and idling and WOT?
Thank you
One reason is definitely that the 5’s are so well insulated. I hear very little outside noise compared to our 3-series.

That said, Bootmod3 definitely allowed me to make my 540i a bit louder. But if you want to really hear it, I think you’ll need to modify your exhaust system. Or roll down your windows. 😉
