Thanks for the feedback, both you and everyone else on this thread.
I found elsewhere in the forum that if you upgrade the headers that you should reflash, and for some reason that kind of freaks me out. I think I'm going to go with used cats for now. If I'm wrong and I should really not worry too much about the reflashing, let me know.
