Yeah I fried my front o2 sensors

if you didn't accidentally unplug the wires or take if off completely, i doubt it's the culprit

RE: LT header problems
even if you are catless you won't go into limp mode unless the front O2's are not working. the downstream o2 sensors are for cat function only. if the cats are removed the rear o2's sense that and throw the check engine light but it will not go into limp mode as long as the front sensors are good.
the front sensors are for air fuel metering and have nothong to do with the cats of what type of manifold you have. if you throw 24lb injectors on the car without a tune the front o2 sensors will sense too much unbuirnt fuel and throw a code and go into limp closed circuit mode. as long as everything is the same and just the headers were changed your car should not go into limp mode assuming the front sensors are fine
