k24a3 k swap 2.5" or 3" exhaust..

was researching exhausts for my h22 setup, many back to back dyno runs from ppl on hondatech found gains all throughout the rev range when upgrading from a 2.5 to 3" exhaust

would a 2.5" inlet. muffler be ok? or recommended go 3" muffler inlet.?

so..

2.5" header. 3" header back to muffler then muffler back 2.5"/3"?

thanks.
