What sort of power/consumption improvements/problems (if any) would I have if I replaced my stock headers with those from an M3? Also, is this even possible? Just checking. Thanks in advance.
What year is the M3? Depending on the year it may fit with minor mod's, I have a 97 328 and tried to use 99 m3 headers that would not fit to the block correctly...
