Are 1M DP higher flowing than 135/335

Having a discussion on a fb group, and Iíve heard from few sources 1M DO are higher flowing than non-M.
We got coupe pics of cats and insides seem to be same from looking at it.

Can anyone shed some light on this?

People say that because they "gained less on the dyno" when going catless DPs than a 135i.
Fact: IKM0S ROM has more differences than just overboost/boost. Obviously the differences are going to be skewed.

It's simple, hook it up to a flow bench and prove it. Everything else is just an assumption.
