Even with catted mid pipes they can still toss the light becuase they flow more and it confuses the computer. And you need to get your codes read it might not be the O2 sensors setting the light off now.
And they do work i have a set on mine and so do my freinds. No problems here for almost 2 years. So if i was you see why the light is going off if it is the rear o2's you might not have them connected good enough or they may be bad.
