RE: Problems installing new exhaust, re: O2 sensors
Would PB Blaster (can get it at Advance Auto Parts) and heat - I usualy use my OxAcc tourch and get the pipe side red hot. Works 9 out of 10 times - that 1out of 10 times the bolt breaks off.
Usually like Murphey's law: "If it don't fit, FORCE IT, if it breaks it probably wouldn't of worked anyways".
Good Luck.

RE: Problems installing new exhaust, re: O2 sensors
I had the same problem on my front O2, was cross-threaded from factory. If your doing pipes and a PCIII at the same time, just get the O2 bolts right away and you dont need to mess with them twice.

At my first attempt after soaking, I got two full rotations before it locked up again. Doing a second soaking right now and I'll hit it again here shortly. At least I know it will come off! LOL.

Seems like this is a pretty common issue and Im just wondering if anyone has said f it and buy a new sensor or is this cost prohibitive and a new 02 sensor really expensive? After all the whacking, smacking, put it in a vice, heat it up with a torch does any of this damage the sensor or are they pretty much bullit proof?

I believe these o2 sensors are installed by a machine at the factory, something I'll have to see if there's a complaint line for someday lol.
An O2 sensor is in the $80-$125 depending on where you get one. So even with some elbow grease it's worth the effort, imo.

It seems so. Finally after a few applications of PB Blaster and some WD40 while making my attempts to rotate, it slowly and painfully finally turned out.

I just got my '10 street bob a month or so ago, have about 2000 miles on it, maybe I oughta try to pull my O2 sensors out and put back with anti-seize now? Or maybe already too late? Didn't realize this could be a problem until finding this thread! Have pulled sensors out of car exhausts all the time with no problems, yeah, need a breaker bar, but have had them come right out so far! Guess the air cooled HD motors run a hotter exhaust, cooks the threads in there!
Could be wrong, but seems I heard that some of those sensors depend on the threads and pipes to provide the ground side of the sensor circuit, so might be sensitive to what kind of anti-seize used. Don't know if the HD system is this way or not, but I generally use a copper based (locktite copper anti seize is a good one) just to make sure.
Sensors like this on cars, particularly water temp and oil pressure, need a good ground to complete the circuit, put teflon tape on them and there's a good chance they won't work. The copper anti-seize has always worked for me.
