ZX6R 2009+ lambda sensor issue

Anyone running a full exhaust without a lambda sensor? I have full exhaust the Bazzaz ZFAM (autotune) at the moment which is causing the bike to throw a code (67) since I need to remove the OEM lambda sensor. I plugged the OEM sensor back in and the code was gone.
I'm now trying to find a way around it and found someone selling a 'O2 eliminator' but it seems a bit dodgy. I also learned that Dynojet has a 'O2 Optmizer' for the euro models (not even sure if that applies for Australian bikes) that is required in order to run their autotune.
Has anyone faced a similar problem? Solutions? Ideas??
