I was going to put my headers on my truck this morning,but I ran into a problem.The rear o2 sensors will not come out of my stock exhaust y-pipe. I bought a older y to put my headers on with so I will not have to cut my stock y.How do you get the sensors out. They only come out about a thread and then stop will not go anymore.What do I need to do.

 

Sounds like something screwy with the threads. I have removed plenty without that problem. But on a different note. What are you using for tuning? I would just turn COT off and plug them on the y-pipe you are using.

 

Hp tuners will be here next week.I gave up on it today.I might try to get it done next weekend.They finally came out the threads were gaulded.
