Default How do you determine header pipe size?

I have a set of Kooks headers that I listed for sale as 1 7/8 because well Im stupid and just thougt that was what they were. I measured them on the outside of the tubing just where they would come out of the head and they measured 1.750 so is that the correct size 1 3/4

Those are 1 3/4", which are still good headers, but I would warn anyone that is buying them thinking they are 1 7/8". Personally I'd rather have the 1 3/4" Kooks unless I was running an FI or large displacement engine.
