Pipe speed controllers

[Paril]

Random thought, would be interesting to have pipes similar to the ones in BC/TD that can increase or decrease the speed of items passing through them - not additively, just like a start/stop kinda deal. One pipe, when items pass through it, speed up by a certain factor, and another pipe slows them down. Piston and Sticky Piston might be good items to use for crafting these, although it doesn't make much sense logically at least it wouldn't be too overpowered since a piston is a fairly decent investment.

EDIT: if an item was sped up, reaching a slow pipe would bring them to regular speed. I don't know if you'd want a slow pipe to slow down items that are moving at regular speed, but maybe somebody has a use case for this, like a mod that would need items passing through at a slower speed.
