This question has been asked repeatedly and there are two schools which seems to never agree; one which says that you need maximum velocity to carry the wood chips and so use 4.00” and the other one which say that you need minimum pressure drop and so use 6.00”.
It depends how big a dust collector you have.
If you have small shop you most likely have a small dust collector with a limited capacity ( like mine a 2HP Harbor Freight ) and for that I recommend 4.00” because you wan to keep the velocity of the air stream as high as possible.
If you have a small dust collector like mine you can kill two birds with one stone by replacing the bag it came with, with cartridge filter.
Not only the filter filters the air much better and stop much smaller particles, which is very good for your lungs,than the bag does but in addition it increases the air flow because it creates less flow restriction than the bag.
You can find tons of posts about this subject on LJs, just make search for dust collector or Wynn Filter.
Also you will find endless discussion about using PVC piping or not.
My opinion is that PVC piping is jut fine for a small shop.
