I've heard that my 06 doesn't have a cat in the up pipe, so would it be worth my while to still up grade my up pipe?

if you want to pass emissions you need a catted downpipe. if not, catless. i would check out Cobb, APS, Helix, Invidia.

I want to go catless since changing the dp over my lube pit home will be a sinch. I know what a bell mouth looks like but was does the divorced part mean?

All-year STI's come with a catless up-pipe.

Like others said, get a catted downpipe if you want to pass inspection.
