What size exhaust pipe? Dakota manifold p/n's?

I know there’s a lot of discussion on this topic on this site. The big pipes aren’t necessarily the better . Think about a garden hose. If you have water coming out of the faucet in a half inch diameter hose and you connect a 2 inch diameter hose to it you’re still going to be limited where the waters coming out of the faucet. You’re only going to get so much volume there. That high pressure coming out of the smaller manifolds is only going to expand and have less pressure coming through the pipes.
