Default check engine light, high flow cats??

I just had two installed and my check engine lights came back on for the 02 sensors. Any ideas why??? I heard i should just disconnect my battery and it should go away, is this correct, and if so, for how long?

My rear O2 codes showed up after I installed hi-flows too (Random Tech). I never figured-out why, I just turned the codes off.

BTW, if the codes showed up the first time they'll definitely come back. Either tune them out or get O2 sims.

Which codes are you throughing? I was throwing heater codes from the back O2's. I wraped the very bottom part of my headers mainly to protect the coating from stone chips and I havn't had codes since.
