Havent seen many exhausts on the G30 so thought I'd share mine. Tried out a quad exhaust on the 530e. Came out looking pretty good and actually sounds pretty decent! No drone and still pretty quiet at freeway cruising speeds unless I throw it in sport
Some pics
Some more info one the build in my thread here
