CEL with Armytrix Downpipe w/ Cat Simulator

[siupra]

Hi all, new user here and looking for some advice.

Been running the armytrix DP w/ cat simulator for 15k+ miles with no issues but recently got a CEL for "12B701 Lambda probe heating after catalytic converter".
Car has 20k miles and running JB4.

Has anyone else had this issue/experience with the Armytrix DP?
If so do you have any suggestions or solutions?

Thanks!

You can clear it with JB4, but it will likely return. It took a long time to show, so hopefully you won't see it again for another 15k miles after clearing

Let your car warm up and get to operating temps before smashing that gas. You won’t have this issue ever in your life.

Cat simulators do not work on this platform for more than a short period of time. There are countless threads on this exact issue.

The armytrix has a built-in one.

I bought their cerakote version and have 50k miles on it with no CEL
