Have a brand new MPE I just got as a gift, but traded in my M3 last week and now have two of these (though the other is sold).
It is a brand new F8X M3/4 M Performance exhaust with titanium tips and mid pipes.
Can be picked up in Westport, CT.
4050 OBO which saves you ~650 on the exhaust and tips alone based on the best pricing I've seen of 3600 for the muffler/mid pipe and 1000 for the tips. Also saves on shipping and tax where applicable.
