Help with code

[ledesma54]

Okay i just put in some LT headers with the mid pipes on my 04 gto, anyway the engine light came on and its saying that bank2 o2 sensor no activity, now is it because i have no cats now i just have mufflers. I have a Cold air intake, a 85mm mass air flow, the predator tune, and 1 chamber flow-masters. What sensors do i turn off in the predator.
Thanks in advance

No cats will throw post-cat 02 codes, if that's what it is turn off the rear 02 codes for both banks. If it's a pre-cat (sensor 1) code check to be sure it's plugged in correctly. You need the front sensors, Predator won't let you delete those.

Take it to a shop and have them delete the codes for the rear 02's. If its a front sensor, you have a problem somewhere. The only problem you could have with fronts is the 02 heater code cuz they dont heat up quick enough with headers.

You have to turn the codes off for B1S2 and B2S2.
