It reduces flow by spreading it out over a larger area, having the spray bar is purely up to you and the aquarium you keep.
 
Well if im a little overstocked is it better w/o it? Also do I just let n shoot water down or do I but the L so it shoots to the side instead of down?
 
I've always been told and read that if you have oxygen problems the odds of flow from a canister fixing it is near none as canisters are highly oxygen exhaustive compared to other filter systems like sumps. If you have oxygen problem either limit stock or seek other methods of increasing oxygenation like an air stone or a power head aimed at the surface.
