I have ARH DownPipes with cats on my Camaro v6 , and I’m getting the cel just for my passenger downstream o2 sensor , i replaced the o2 sensor and after disconnected the battery and stuff but after 10 miles of driving the cel came back on . Any suggestions on what i should do ? Thanks

Two things you can do, add defoulers to your o2 sensors to make them read less exhaust gas.

Or you can have your tuner disable the codes.

The fact that you have this issue with the catted downpipe is weird tho maybe try contacting ARH.

I have the catless downpipes from ARH and I had these error codes for both banks p0420 and p0430 and even after installing defoulers they still appeared so I had to get my tuner to disable the codes via tune.

Hope I pass emissions 😛

First I'm trying to fix it without disabling the code that would be my last bet, i tried contacting them but not a word back. If i was to add defoulers do i add them to just that one o2 or both sides? I’m just very confused on why I’m getting the check engine light still when i got cats still and i replaced the o2 sensor lol
