best suggestion is the software imo, then for emmisions just get some high flows installed, and run some emissions stuff in ur gas.
Where would I find the software? Or who offers it?

So you are saying aftermarket headers + Magnaflow Spun Cats = no Cel.

Will it pass emissions/smog?

Checked it after driving a few hundred miles and no codes...I would say that is a Pass for Emission.

I heard that certain race cats would not pass even though you didn't get a cel. I guess we won't know for sure until someone tests the Magnaflow Spun Cats

I still haven't bought my cats LOL - I spoke to my race shop and they suggested that I go ahead and put them with the install. I'm still torn whether I should go 2.25 or 2 for the cats....

Error on the side of larger. That's the only advice I can give you. They'll flow better than the 2"ers. Now as for whether or not they'll heat up at the same rate and therefore work as well? I have no idea!
