A plenum is usualy the first piece of metal on the outlet of the furnace, the trunkline is any ductwork that follows.

If you are using a horizontal built up air handler, you may not need a plenum, the main trunk screws directly on the air handler discharge opening.

Establishing a consistent pressure and smooth, uniform flow is what needs to be focused on, plenums are sized for and used to establish both, so that distribution of the air can be predictable.

6" flex, will give you a high static pressure, if you try to move 100 CFM through it.

You may be looking a duct sizers that are intended for use for sheet metal.

You may be confusing static pressure and friction rate.

They are not the same thing, and that misconception, has harmed more furnaces then not.
