post catalyst means the o2 sensor after the primary cat is reading badly.. check for exhaust leaks where they cut the secondary's off.. secondary cats are so far away from primary's there is no way the o2 sensor right after the primary cats is reading that data.. unless you have some sort of exhaust leak or insane amount of back pressure forcing exhaust back towards the o2 sensor. Could simply be a bad 02 sensor as well its only reading bank 2 not both.. And rich mean its getting more fuel then air.. everything you have done would make your car run leaner not richer.. somethings off.. put your stock TB back on pull the negative terminal of your battery and reconnect after 10 minutes and try again.. that will clear the code see if it comes back.
so a few things in summary here I dont see where it says you removed your secondary cats... not sure where nsx matt is getting that.
There is a good way to check your sensor.. swap your 02 sensors from left to right and see if the opposite bank fails.. if it does its a bad 02 sensor.
put stock TB back on clear the code with negative battery terminal pull and reconnect.
hope this information helps a bit.. Good lesson in doing 1 thing at a time if you install 20 mods you have 20 mods to trouble shoot.
If you do not know what im talking about as far as primary and secondary cats the primary cats are right off the block about 8 inches down there is a o2 sensor before and after those cats.. then a ways further about under the rear floorboard where you would put your feet are your secondary cats then you have your x pipe before your rear cradle/differential..
Sorry I am a bit all over the place. ..
