Do you know if the ACS exhaust from an e6 M3 will fit on a Z4M?
I assume it should be the same but the size difference between the two makes me think it might be different.
mmmm it will fit of course but the modifications I think will be many - If you google pics of both you will see the differences of the undercarriage are fairly different. what is the profile of the Pipe you have in mind. as you can see below standard Z4m the first two then e36 m3.
