DId you make sure the 02 sensor is plugged in? Also, did you tune for the new headers?



yes there plugged in and i did have my pcm tunned for the headers.. i wont really know the problem till i get my full exauhst on

but as of right now i think it is just throwing that code because i am running straight headers no y-pipe.. so the cold air from outside might not be letting my o2s get hot enought to ready accurate
