Default What do these fault codes mean?

I just got the fault codes 16805, and 16815. These codes mean warm up catalyst efficientcy below threshold. What does this mean? I think it has something to do with my exhaust, but Im not sure. Ive cleared the codes but they keep coming back, what can I do so that they will no longer come back?? Thanks alot

Doesn't that mean you don't have cats?

Default Sounds like you got your answer then......

...I'm no expert, but it sounds like the codes are being thrown due to the lack of catalytic converters.
