 I would like to put a Square out pipe after the VAM. It would be easier to mfg. 
What if I need baffeling, or muffling after the VAM section?  

Square pipe is good. According to the Russians a very cost effective
way of muffling a rotary. PL

Will it stop the process of cooling the outgoing exhaust?

We don't know Jerry. A temp sensor at the air inlet to the muffler should
tell the tail. PL

I will try it without baffeling or muffling first.

Won't hurt. PL

Should I put the Ox sensor at the  bottom of the VAM? 

The O2 sensor should go into the main can as the outlet is mixed with
fresh air giving a lean indication. PL

Should I put the EGT probes on the out pipe?

The EGT probes should go on the exhaust inlet pipes. PL

Should I put a pressure probe into the center pipe for checking air 
speed at the inlet?

Good idea. PL
