My real question... Do the new headers come with new precats, or are the precats eliminated with the new headers ? If new headers will most likely solve my problem then I think that would be the way to go since precats will cost a few hundred, I might as well spend a few extra dollars and get the performance boost.

Thanks,

Or if you don't want to replace the headers you could try a new sensor first.



If the precats are clogged then a new O2 sensor wont do anything, like i said "IF"
