just ordered pacesetter LTs and off road Y
You will either need some o2 simulators which can be found at a sponser----->
or find a shop of some sort that can tune the rear o2 sensor out. I would recomend a tune, considering i got mine done for 75 bucks and o2 sims are around 80 or so depending on where you get them.
I also got him to do some other things besides just taking out the emissions codes. (all the SES light is doing is letting you know something has changed with the exhaust from factory settings, you won't loose any performance)
However, it is still highly recommended.
Good luck with the headers!!!
