Also, they will not directly bolt up to the rest of your exhaust. Exhaust will have to be custom made at the very least a connection from headers to cats.

The car sounds like a pure bread race car with the headers, high flow cats and muffler set up you will not be disappointed. The power increase was dramatic. I think the benefits are far greater for those like mine with vanos...this removes the pre-cats as well.
I know you are in Newhampshire, but do you know if the headers are CA carb certified? Also, what do you mean by 'MAF' as a mod?
In terms of the 100 cell cats, the lower the cell count, the better correct? Which cats did you use and from where?
