Just before Christmas I purchased some Kooks long tubes with the Jet Hot coating and a catted Y-pipe.

Well, it's true that the new coating will kill O2 sensors. I just had my SES light come on and it was P1134 (insufficient activity Bank 1 Sensor 1). I installed old O2's in the headers expecting this....

So, is it now safe to install my new ACDelco O2's? I've been driving the car constantly for about 2 weeks now. I would guess the coating should be done curing, but just wanted get some input from those who have been through this before.
