The Mechanic stripped the threads on mine when he was putting in my UR testpipe. I had my Welder friend put a quick tack weld to make sure it doesn't pop out and drag down the road (Yes it still works after the tack) All is good now but If it needs to go in for major service I will need to buy another O2 when I put the cat back in. I have read the sensor wire is 6 ft long, where does it connect too, is it hard to replace?

 

It connects under your passenger seat, VERY easy to dissconnect and reconnect
Do you have an 02 fix so you dont throw a CEL? if so, unscrew that, and screw the entire setup into your cat converter when you want to get smogged, problem solved

 

thanks for the reply, The UR pipe comes with a extended bung so I did not need the O2 extender, wish I did now,lol. I found one at oxygensensors.com for 150.00

 

Yeah it sucks that things like that happen.
When removing my Downpipe and cat I was so worried about stripping the studs on the exhaust mani that I didnt pay much attention when removing the rear 02 sensor. So now its kinda torqued down into the 02 fix and I hope it will stay that way. Good to know that I might be able to de-thread it and tac weld it if necessary.
