Guys I need your help on this one and I did do a search on the fourm. I had a p0138/p0139 code and I chech it with my code reader and change my rear o2 sensor. The problem that I got is that the pipe that comes after the rear cat that holds the o2 sensor is stripped out and I need to replace it. Were is the best place to get one or should I try a local junk yard. You guys have been great and i've done alot of work to my car because of you. Please Help!

 

so its just the o2 bung thats stripped? just get a muffler shop to put in a new bung and plug the old one up.
