Hmm.
BMW engineers have however gone on record advising that they were attempting to create a unique exhaust note similar to the S54 for the M2..

I haven't read this before. Do you have a link to where this was said?
IMO, the N54 and S55 sounds more similar, due to both having twin turbo and true dual exhaust to the rear muffler (both engines have exhaust from cyl 1-3 and 4-6 basically separated until the rear muffler). Unlike the N55 which has a single turbo and single pipe exhaust, mixing exhaust from all 6 cylinders though the one turbo and one exhaust pipe.
