I fear you may have missed the whole point of having an easily accessible pre filter. Many folks seem to give their pre filters a rinse once every week or so. Mine certainly don’t get very clogged as you put it, in a week or even two.
As for saving a few pennies on a piece of pipe that might compromise the efficiency of their design seems highly unlikely to me but anythings possible I suppose.
I may try fitting a larger pipe at some point but I’m not expecting it to make any difference. It’ll be a nice surprise though if it does.
I can't help but feel you're labouring the point unnecessarily here. You can cut extra holes in the pipe, or swap out the pipe for a larger pipe, or do neither and leave it as it comes in the box. It's not exactly a big job either way, and its a minor modification.
I find the extra holes help and maintain consistent flow for longer, your personal mileage may vary, and will depend entirely on the type of tank you are running - so just do (or don't do) what you feel is best for your situation.
