I wonder if porsche has something up it's sleeve for the possible filter version to compensate any performance drawback that it held back on the pre-particle filter version for this reason, like a little engine tweek. I would be more worried about the possible changes in sound since 10HP more or less is not going to be very noticeable, and a possible worsening of sound may not be easy to compensate if at all  .. we will likely only know when it's too late to get a pre-sept unit if its more desirable.
