I need to replace my driver-side front O2 sensor (bank 2, sensor 1,) and while I'm doing that, I might as well replace the passenger-side one as well. My question is, do I have to unbolt and lower my exhaust, or is it possible without lowering it? How hard is it to replace it if I don't have to lower my exhaust? Obviously if I were to remove my exhaust, the O2 sensor would be a breeze, but boy, getting the exhaust off is always a pain, especially getting that damn screwdriver in there to unclip the O2 sensor from the top - although I know I have to unclip it regardless when I'm changing the sensor to begin with lol.

So once again, is it possible to change the O2 sensor while the exhaust is still installed, and if so, how hard is it?

nah, you can do it with the exhaust up there, you just have to reach for the plug because its right near the top of the transmission

use a 22mm wrench if you dont have the o2 sensor sockets, its not that hard really

To me getting to the Front O2's with the midpipe still in a PITA. I'd drop the midpipe and do it easy from right there. Also O2's for our cars are pricey...

Id drop the mid pipe too. Pass side plug is a pain to reach with the midpipe still in place. If you drop the mid pipe half-ass itll give you enough room to reach up in there and unplug it then you can drop it all the way.

You can do it without dropping the exhaust, but its not easy. The clips are a bitch for sure.
