Unable to get my damn sensors off. Soaked them in PB, and they are locked down hardcore. Gonna have to torch them probably, but for those who have replaced them? What was your easiest way to change the passenger side?

back before I put my headers on I had to change the o2's and my driver side took less then a minute and the passenger side I had to cut it in half so I could put a socket on it and just use some muscle...

There's not much you can do besides use heat and pb blaster. You want to use a socket or closed end wrench on it so you have as much surface area on the nut as possible. Since they are being replaced, cut the wire so you can put that socket or wrench on it.

Cut it and use a socket, as said. Regular wrench won't get enough torque on it sometimes.

Try and tighten them first to break it loose. Works more times than you'd think. Bolts too.

I used PB bllaster and ran the engine for a few minutes to heat up the exhaust pipes. Still took some muscle, but it came out.

when i did mine on the passenger side i soaked it in pb blaster got a wrench on it couldnt get it to budge so i moved the started forward enough to where i could use another small wrench as a cheater and it came right out.

I had to use heat on mine, when I had stock manifolds.

PB, Heat, 7/8 deep socket, six pack of favorite beer, and a little luck.
