Noop. The N54 and N55 mid pipes have the same rear(box) resonator. The N55 mid pipe does not have the secondary cats(which the N54 and 1M have) - which restrict flow somewhat.
The 1M has secondary cats in the mid pipe(just like a N54) but the resonator box is a fake. So that is why its more raspy. ie:drone. because the 1M's resonator on the mid pipe is fake. The pipe just continues thru the resonator/box.
