2.5" vs 3" downpipe

how much of a difference do you think a 3" downpipe will make when im only making about 250whp? 2.5" will be so much easier to make but if you all think i should still go 3" then i might.?

3 inch is better, but not need for 250whp...

you see a little better spool though with the 3inch
