Great example of why you should take your cars to the experts at StanceFactory...even though Mike is admittedly not an engineer

I'm glad the people who bought euro silencers from me were not customers of theirs.

@Zimmie - I said it was heavier, not lighter...it weighs a ton

Euro M3 3.2: http://realoem.com/bmw/showparts.do?...15&hg=18&fg=20

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...

both mufflers reduce inside the muffler down considerably. but this is to keep the cooled exhaust velocity up. If I was op I would just get an after market unit and call it a day unless you are hell bent on having that 1000lb euro behive.
At this point it's a matter of finances. If I can get the exhaust system bolted up for 100 bucks so much the better. Course now that I consider this the UUC catback is only 600 shipped, but it would still need to be hacked to fit onto the back of the EURO mid-pipe

the na part numbers are wrong on real oem.

if you order those parts they will be too big for the us spec e36m. those new part numbers are for the e46m and it got rolled into that for some reason.

the proper us spec numbers are
18-11-1-719-446 and 18-11-1-723-720
