Seriously need help fellas
After I installed headers, P0430 popped up along with a misfire code for one of the cylinders. I installed the O2 sims shortly after that and have not had the misfire code since. So the two could possibly be linked to one another
If you have headers installed on the car make sure the O2 simulator/conditioner is in place and functioning properly. If not it may be time to replace some O2 sensors.

If it were me, I would get the P0430 taken care of and then see what pops back up.
P0430 usualy pops up for one of these reasons:
O2's are ageing and getting slow/lazy
catalytic converters are bad
exhaust leaking
If you know how to operate a multimeter you can subscribe to the toyota techinfo site ($20 2day access) and diagnosis it
