Hello,
I´m soon to become a 640d owner
It has all the right features except for the exhaust pipes. It has the M-package but the exhaust pipes are round. I would like like to change to rectangular. The problem is that when you search for part number for the diffusor it shows the same number for all F13 with M-package.
Can somebody tell me the part number for the diffusor for the rectangular exhaust?
Thanks you
