The original owner of my 08 335i did the muffler delete. Not overly loud, although my wife swears she knows exactly when I leave for work early in the morning.
My only complaint is the drone that is very noticeable inside when on light throttle in 6th from about 1800-2400 RPM. Looking for a way to reduce/eliminate the drone with either an X-pipe or adding small mufflers like Magnaflows. Any thoughts?
