I am not sure if it's the resonator because there is a resonator with the OE pipe too but there is also the cats which N55 mids don't have. Somehow, it flows better and minimizes the drone. Of course, resonator might be different as well but from the looks they look similar. Check photos of both from my install thread, post 2:
