^This. You couldn't pay me to run the stock 6 catted pipe on my car, no way in hell. Unsure what the CARB laws are for aftermarket H pipes but as long as a componenent has a CARB number on it its good. CARB is ****ing stupid btw... At any rate, swapping midpipes is a 30 minute job. Swap back to stock pipe on emissions day, leave all the tools/ramps right where they are when you are done swapping, drive to inspecitons station, pass emissions, drive home, let exhaust cool down for 30 minutes and then swap back.
