Yes, it will work for the 1M. The 1M has higher flow main and secondary cats... but still getting rid of the secondary cats will free up the exhaust flow.
I believe the N55 mids also solve the 1M's exhaust drone. The reason is the 1M has a "fake" resonator that is hollow(no fiberglass packing/sound deadening) while the N55's resonator is functional. See my link bellow...
found out something interesting about the 1M exhaust...
