No science (or very little) here either but I used 1.75" headers into a 2.25" collector w/ 2.25" in/out of the Spintech.

Thanks Tracy.  Those numbers certainly sound reasonable.  I'll try to remember to look at the actual size of the exhaust port today, and see how that compares.  Maybe I can think of a way to turn this into a cooling question, and then Ed can calculate it for us :-)
