It is in the muffler. Has been confirmed, reason for the new large muffler. Also look at the Mperf parts list, two different exhausts. Europe version has the filter(M2C Mperf exhaust is only rear section).

Is the particulate filter the reason the muffler is so large and will USA cars also be equipped with it?
BL: Yes, the particulate filter is the reason the muffler is so large at the back. The U.S. market will get an exhaust WITHOUT the filter. The filter is ONLY for Europe. The M Performance exhaust will also get the OPF filter installed. The U.S. market will NOT get the filter on the titanium M Performance exhaust.
