CEL, even with defouler?

[nerdrum]

I'm having a really odd situation. I've had my RH on for probably about two months. Never had a single issue with it, recently the flexpipe started to crack a bit, which was expected since it's a dc setup. I ordered a new bigger flexpipe that i'll be welding in place pretty soon. But, recently my check engine light came on, a buddy of mine came over with his ODB-II reader and i can't remember the code but it had something to do with the o2 sensor in bank two? I believe. I'm not entirely sure.

Could the exhaust leak in the flexpipe be causing the CEL? The weird thing is, If I reset the battery and just drive the car normally -- it doesn't go off, no matter what. The minute I drive "spiritedly" it goes on about ten minutes later. I haven't done any mods recently except a skunk2 70mm exhaust which definitely isn't the cause.

Does anyone have any suggestions on what I should do or is it pretty much caused by the leak?

Do you have a defouler now? That exhaust leak could definitely be screwing things up for you. Get that flexpipe fixed and I would go with an angled defouler, if you don't already have one.
