I about to order a set of long tube headers and my question is if I run my stock o2 sensors will it throw any codes or will I have to do a custom tune and delete the o2 sensors? Thanks for any and all help

If the long tubes or their Y-pipe don't have catalytic converters ("cats"), then you will get "Catalyst Inefficiency" codes. The cost of a tune is cheaper than cats and there will be many other benefits to a custom tune other than just turning off the rear O2 codes. A good tune will optimize the headers, anyway.

ARH or Kooks will fit with no issues and you can either buy them with cats which don’t require a tune or no cats in which you need a tune to delete the downstream O2 sensors.
