Stock exhaust size? 1986 K20

I have been unable to find a good diagram showing the exhaust system for my 1986 K20 350; I know Walker has good diagrams, but everything I find is about 1"x1" and I cannot read part numbers or pipe sizes. I need to know what size the exhaust is that comes off each manifold so I can buy additional pipe and fab up a cheap system. It is a dual system; no y-pipe. Thank you to whoever can help me.
