Default headerback install CEL

I just installed my MRT header, highflow cat and brullen catback and after of driving for a day with no problems and no CEL, this morning on my way to work, my car started to bog and hesitate. It has an eratic idle. I scanned it and it pulled a P1137 for air/fuel monitoring. Could this be caused to my CEL with my front O2 Sensor. Any ideas or what can help me

Is the O2 sensor plugged into the cat?

Definitely is because of the placement and/or hi flow cat. moving the location of the sensors will change the flow they see, plus there is the change in flow because of new pieces. Probably no way around that CEL situation, unless you can maybe get one of the CEL fixes to work for you.

i just got back from lunch and with the battery being disconnected for an hr and a half and after taking it for a drive and getting on it pretty good and taking it on the freeway it drove fine and no cel yet, but the cel didnt come on till 2 days later after the install, so im thinking it will just come back on in a few days and the problem is intermittent.
