Damage to O2 sensor if I cut exhaust pipes?

    I am going to be removing/replacing my transmission with a new transmission and transfer case soon but have a question about the exhaust. The pipes are in the way right now and rusted pretty hard core so un-bolting is not an option.... will it do any damage to the o2 sensors if I cut the pipes off behind the cats at the closest hanger? My intent is to get a new exhaust system and headers down the road but for now I just want it out of the way...

    Wow!, Just curious why a 2010 needs a new tranny and Xfer case? As far as cutting off the pipes and the affect it will have on your O2 sensors depends on what state you live in. Why not replace O2's at the same time so everything is up to snuff at the same time? Or are you talking bout the 2002? Big difference. Otherwise Ditto.

    If what you are planning to do is cut the pipes and then simply use a sleeve or such to weld them back in, it shouldn't hurt anything. I assume this is on your 02 Tundra? Don't remember exactly where all the O2 sensors are (there is like 4 of them), but as long as you put things back close to where they were all should work fine.
