ditch the up pipe cat. Even the smog cops in CA wont notice that (and wont be looking for it) and it will still pass emissions just fine.
For a downpipe with a high flow cat, look no further than Stromung, I think Scoobysport and Also Perrin mankes one.
I am 99% sure you can set up a STromung system with a high flow DP cat AND a high flow center cat.
