I thought you were talking about regular NA muffler - not NA PE
The NA PE muffler has bigger than 3" tips on it from the start (at least they do on my E92 version) and they fit in the diffuser fine.
I don't think they are 3.5" though - somewhere in between 3 & 3.5
I could get measurements once back home...
