Dunno how many miles you have currently but keep in mind even w deletes it takes 300/400 miles before you see the cel. Not saying you are getting one just that a lot of times people get fooled initially. I know someone w same cats (older gen)that it took 1K miles before the first cel. They sent an updated version after but it happened. Hopefully it’s full sorted now.
It is quite different of where the oem sensor goes into the cat vs the aftermarket ones.
Would that be the trick to not set off a cell because of how/where the oem was located. It seems right in the center where the honeycomb is? 🤔
If some one can design one that can mimic the same effect may actually solve this issue?
The OEM cats have multiple bricks inside with a space between them to my understanding and the OEM sensor is between the two.
In that case the sensor need some back pressure/flow restriction for the sensor to read properly so it seems. Most aftermarket cats put its sensor towards the back of the cat where the exhaust gas flow without any restriction exiting the cat. Could this be the reason for the CEL lazy/delay 02 reading? Worth exploring. I have an idea and will give this theory a test to find out if this is the case.
Update: I DO have a CEL , code P0430.(all 3 codes are the same) . I have a new O2 sensor enroute and an extension to add on it.. my understanding is this will solve the problem.. ironically the CEL comes and goes.
Either way, I’ll do the extension and new O2 sensor

All the aftermarket cats have the o2 sensor located in the rear. Perhaps to maximize the filtering before reading the co2?
Soul had a previous design which had a second bung where you could adjust how much air could enter/exit the cat. Looks like they dropped that idea.

I hope that eliminates the code, but if the sensor was working just fine before doesn't sound promising.

Just a theory. Can we not have 2 substrate ie. 200 and 700 cell build within the same cat?
I would have the 700 cell in front of the 02 and the rest can have the 200 cell. Almost like having the mini cat in the adapter idea. Perhaps in a separate chamber where the 02 would be. In theory, this could work if it can be executed? Is it plausible?
Like I said, just a theory and I have zero idea how and what is involved in putting a cat together and cost. But if I where an aftermarket company, I would explore this idea if it hasn't already been done. Perhaps a patent.
My understanding is the reduced flow of the 700 cell section would ultimately constrict exhaust flow, largely negating any benefit from the 200 cell section.

Correct but I was just suggesting perhap using a small area ie. 20-25% of the diameter where the 02 is located if plausible?
I would be concerned with moving the factory O2 sensor just to avoid a check engine light. The car stays in closed loop all the time so that sensor reading is important for the fueling even at WOT.
The downstream O2 sensors in the cats only monitor the exhaust for emissions. The primary O2 sensors in the headers are used for fueling purposes.
That’s not true anymore for the C8. Car stays closed loop even at WOT. The O2s are wideband sensors now similar to the AEM I ran in my racecar to keep tabs on hot races.
The question is how much or what portion of the exhaust gas does the 02 sensor read/detect from the diameter of the whole catalytic converter?
How about putting a small diameter 700 cel in front of say 02 senor and keep the rest of the area open like a straight pipe? Think of it like a small cat inside a larger diameter straight pipe for flow/performance?
