Well today my car attempted to go through inspection, but no dice, the person that had it before me removed the O2 sensor behind well on the back of the cat and welded the hole shut, now im faced w/ a dilema

Can i make a hole anywhere in the cat and put the sucker in

Can i put the O2 sensor in the piping somewhere

Can i just place it close to the cat so it gets hot and will it work

can i wire it into the O2 sensor in front of the cat


someone help me with ideas

 

go to a muffler shop and have a new O2 bung welded in.


where are you located?
