everyone says bigger is better, but if you're running stock internals like me, you can't go wrong with 2.5" piping all the way

Lower boost levels I would stay with 2.5inch all the way, but anything more then like 10psi I'd go with 2.5 to 3inch or 3inch all the way!

you can go 2.5" dp then 3" from there back. Most 3" dp will not allow you to use AC.
