How long have you been running the modified exhaust and how many miles on your car? Any other mods, ie CAI, tune, etc?

Could be the rear 02 sensors going bad. They are only good for about 25K to 50K.

How did you find it? I am curious because I am getting the same code. I replaced my 02 senors about 6 mths ago, so I doubt it's them.

Usually it's the rear/lower 02 sensor that goes bad.

P0420 and P0430 are just catalyst effficiency codes. Your new cats are likely just flowing too fast. A new sensor won't fix it. The only way to get rid of the code is to disable those rear O2s.

I wonder why it took a few months before I started getting codes?

Try switching the 02s around. Rears to front etc.. That way you will find out if you have a bad one. Im not 100% sure but I think the front sensor is used to adjust the mixture and the rear shows if the cat is working.

You are correct... All four sensors are the same.
