While trying to get off my old exhaust pipe, I couldn't heft one of the bolts off that hold the o2 sensor, so after trying to wrench (stripped), cut (didn't work), I eventually just cut the o2 sensor wire and bought a new one from 22rePerformance online, a great spot if you need new OEM parts for your 22re.
