Is the resonator at the end of the N55 really that much bigger than the N54? The bushings didn't seem to be bigger, it was just their construction thwat was different IIRC.

I believe that it's differently configured than the N54 resonator.
And, it's just not the subframe bushings; the 1M has an entirely different subframe and diff than the 135i. As you know, it's off of the E9x M3.
