If you make the discharge pipe larger the pressure on the discharge of the pump should go down and the capacity of the pump should go up.
Make the pipe smaller and the pressure on the discharge of the pump will go up and the capacity of the pump should go down.
It is the equivalent of opening your kitchen faucet up more or closing it off some.

When you increase the size of discharge pipe, the frictional losses reduce (thus head reduces) and flowrate increases. The frictional losses again increase due to the increased flowrate.
This is not a problem for non overloading type pumps but motor tripping occurs with overloading type pumps.
When you reduce the discharge pipe size, frictional losses increase and flow decreases.
You should note that pump always runs along its performance curve.

If you mean the Maximum Head, there will be no effect because it is measured with no fluid flow. If you mean the Head at a a certain discharge rate then increasing the discharge pipe size will increase the flow rate for a given head or vice versa for a given flow rate the head will decrease.

it will take more than my brain to give you the correct answer.
