im about to modify my N55 midpipes to a Y pipe magnaflow,
if you say the mid-muffler is a dummy, than why would i do what i planed?
and why does the BMW PE has a Y pipe in their kit, if the mid-muffler is a dummy?
or is it a different story for the n55 midpipes?

No. You have things mixed up.
On a 1M, the resonator just before the mid pipe goes into a "Y" is a fake(dummy) resonator.
The 135i does indeed have a
real resonator, not a fake one. BMW's PE(Performance Exhaust) kit includes a Y-pipe to delete the 135i (functioning) resonator.
No, my friend did not take any pictures. But he did say he now knows why his new exhaust isn't as loud as he thought it would be.
