No. Have it disabled or live with it--common with aftermarket cats.

I just got this code as well but I'm stock. It's "low cat efficiency bank X" or something like that. I can't remember which bank though. It definitely won't hurt gas mileage, power, or reliability and is just an emissions thing.

The cat is starting to lose efficiency but hasn't completely failed, or the O2 sensor behind it might also be starting to fail which can also throw this code. If you're tuned, just remove the code in the tune like others have said. Don't take it to the dealer with aftermarket headers and cats.

Go down to "6-19-2012 – A Mind is a Terrible Thing to Waste" and it explains it how it works a bit.

Turn it off. Depending where you live, if they do an ODB test, it wont pass.

Agreed , just turn it off , obd state test will never see it if it's off

If it's on and you have an error , then it will see it


Has nothing to do with performance

Here in TX, if they are off, it comes back with a "Not Ready" state.

I will add that TX also allows for 1 not ready to pass.

They can be disabled totally in a way that will not show up at all.
