Help CEL after a year with GTM RTP

CEL after a year with GTM RTP
Ive had my GTM RTP's for over a year now and never had a problem with any CEL. But recently, within the past month or so ive repeatedly gotten a cel for the cats. I'll reset and it will turn off for a day or two. Then it pops up again, usually while cruising on the interstate. Is it possible that the resonators are allowing a little more air flow through them and thus triggering the sensors due to much air flow? Can the sensors themselves become dirty and thus think there is a block and too little airflow? I thought about the steel wool but im a little worried about it working its way into the exhaust and causing a problem elsewhere. And seeing as they gtm pipes already have an extended bung, i dont think i have enough wire to put another extender on the sensors. Any idea's why this is happening a year later??

I checked the flange bolts. Those are solid as hell. Ive heard stories of cat failure and pieces of it getting sucked into the engine. It makes no sense to me seeing as how its an exhaust but ive heard of it happening. Yea, of course it makes sense to me that if the wool were to come loose it would be ejected out the exhaust, but when you start stuffing material into your exhaust....my mind wonders haha.
Also, should i unplug my battery and let it reset? I just installed the wool and the light is still there. Should i drive it around a bit and it will go off or should i do a reset?

if you are tuned that is the reason for the cel.
had same thing every couple of days,maybe every 3 to 400 miles.
removed tuned,has not come on since.
driven over 1k since.
good luck with the steel wool,curious to know if that works.
since I have to bung extender x 2 welded tofether & it still was happening.

I'm pretty sure that it's physically impossible for it to get "sucked up into your engine" since exhaust gasses flow out from the engine, not the other way. And if it did come loose and get blown downstream, I don't personally know if any harm that it could do. It's just a very fine wad of stainless steel wool It's not going to create any sort of blockage. Maybe I'm wrong though. But I have no CEL.

Bump.. The shop installed my GTM RTPs and now I'm throwing CEL P0420 which is the famous code (along with P0430) for HFC/TP installs.
Anyone have any input? How do I know the sensor is not bad? I have some live data from my sensors but I'm a noob and I don't know if they're reading right.
Any info or help is appreciated!
