Was wondering if anyone has or knows if these headers are worth anything?

I keep getting SES light for code PO431, warm-up catalyst efficiency below threshold, and am assuming that it is the front precat dying on me. I replaced the o2 sensors awhile back with the same code popping up and it didnt make it go away.
I am frustrated because I live in dumbass Cali and nothing is legal here, I want flow, but I can't get HFCs and be legal here, not to mention the cost. I figure I could put on these headers, they should fit, and get the most flow for the least hurt to my checkbook. Swap them out when smog comes along and swap back after. Looked for and couldn't find a test pipe for the precats, and headers should be better than just tossing on a test pipe, good headers at least.
If the headers I linked are crap is there any others that aren't that could be had for a decent price?
I assume that if I fashion a test pipe for the front precat and leave the rear precat as is that might create an issue with it being unbalanced? Free flow on one side and lots of back pressure on the other, please correct me if I am wrong that it would be stupid to do that.
Lastly, sorry I know I have already written a lot, is there anyway to clean a cat that is becoming plugged? I tried seafoam years ago with no change and before I read about the seafoam debate. Also I don't want to hollow the cats out, heard that it sounds like trash not to mention turbulence.
All help is appreciated, thanks guys.
