I just purchased my E60 M which is in route to me and am already buying up some parts. I need to know the diameter of the exhaust tubing pre-muffler so that I can order my cutouts and get to work when the car gets here.
I am planning to delete the outboard mufflers replacing with a cutout and straightpipes so that I can close off and have a civilized note when needed and be open for power and sound...
anyone know this info?
Thank you,
Robb
