Readiness and JB4

Did you check for a JB4? Might be as simple as removing that to get "ready" status.

I'm struggling to get the car ready after replacing the cat-*** downpipes with the stock ones and reflashing it to stock. The JB4 is still in the car but it is by-passed. Could this be the reason why the O2 sensor and Cat are still "incomplete" ?

If you already went through the same path and figured out a way to get readiness, pls let me know. Much thanks
