The mufflers are different, but look at the gasket rings (#3, #4). They are common between the two. Smaller of the two is 68mm ID. Only BMWs that share these rings besides the E36 M3s are the Z3M, Z4M, and E46 M3.
Based on this I made the mistake of not having the euro muffler sent over with the midpipe. This is actually a mistake on realoem. The outlet of the EURO midpipe is actually 60mm. The output of the NA midpipe is considerably smaller probably around 55mm.

I can't see how it is possible to use the same gasket...
