I would think with the intake you would want to have the largest ID at the filter and the smallest at the TB. That way you can increase the velocity of the air flow into the manifold. If you have restricted sections (by the MAFs) you will be creating a vacuum that prevents the maximum amount of air from flowing.

So I would think you want something like 2.75" - 2.5" - 2.35".
