Replacement exhaust manifold questions

[nrose07]

So my stocker is cracked and looking at options. Everybody says they don't notice a difference with a 3 piece but a ported stock manifold people notice a difference. So I'm looking at a DAP and spending more then I want, a cummins manifold that is almost the same price as the 3 piece, or a cheap dorman/skp that I port match. Opinions?
