997 T plenum

A question for anyone who has installed the 997 plenum: how did you compensate for the large difference in diameter from the plenum outlet to the manifold? There' a 9mm step there and only a short distance to make it. I've ordered some step-down silicone hose but think it's going to be too long to work.
