check engine light, help

Hey guys. I need some help. I replaced my oem catalytic converter with Berk HFC about a week ago and last night the check engine light showed up. I haven't check to see what code it was, but does the Berk hfc cause the check engine light? I'm thinking could it be the o2 censor? Im due for smog check in two weeks. thanks.

I'm betting its the O2s. https://my350z.com/forum/vq35hr/5173...flow-cats.html

That should cover it.

First I would get the codes read so you really know what is wrong.

thanks guys. Replaced o2 censors already still throw code P1283. Could be a leak somewhere.

P1283.... bank 2 lean out. Most likely due to the high flow cat(s).
