Looking for info on headers

I'm considering making my own headers for my 3.0 and have some questions for you guys who have aftermarket headers Downey, NWOR, Throley doesn't matter. here's my questions:

Size of primaries? Just the diameter is fine, length isn't so important for what I want to do.

Final size of collecters.

Thats pretty much it. Cheers!
