Alright check this, i took my lance to a muffler shop to get my greddy catback installed and i told them to put my o2 bung on my sensor, and we look under the car it was pretty melted, and im not sure if it is becuase my kamikaze header and dp, i might have to get a new one ,but will this keep happening?

 

First time I hear/read that. Got a picture of the sensor?

 

naw not yet, ill ask my dad for his cam..

 

Did they weld the o2 bung on with the sensor attached?????

 

I don't see how this is possible. I bench test o2 sensors with a MAP gas torch and that is MEGA hot. They messed it up with the welder like someone said. Your exhaust did not melt it.

 

i have extra o2 sensor!!
pm me if you want it!!
