o2 Rear Sensor - Exhaust Problem

[sleepy2lazy]

Thanks Ecoli. Yea, I noticed that the check engine light came on. I thought it might be due to the o2 sensor. The spot on the midpipe for the o2 sensor hole is uncoverred.

Do you guys know what i can buy off the bat from a hardware store that can fit in its spot?

Thanks for the link rst95. I'll probably do that during the summer.
