Am lookin to fit manztel inlet onto my x16xe, but i've just fitted a 4-1 manifold, i heard they work better with a 4-2-1. Is there a noticable difference or is it not worth my time putting one on with this manifold?

A mantzel pushes the power up to around 4.5K. Before this, the engine is near normal if there are no other mods.
A 4-1 manifold will give top end increase, and a 4-2-1 manifold will give mid range.
I put a 4-2-1 on mine. I did this because i don't screw the shoot out of my car everyday and spend most of my time in the mid range. Depends how you drive i suppose.

theres no massive difference between the two until you get to the point of proper engine management and mapping.
but even then the difference is minimal.
