Dealer also switched out my battery and bill is now $700, so they will be adding $1200+ to the bill with those o2s.

Also, would these be the right sensors? at
You can do it yourself. You have to take off your down pipes. 1st time doing it took me 5-6 hours. Now I can do it in about 2 hours on a lift.
