Rather than a Amazon special $145 I went to Ryan muffler in Florence and also purchased new sensors. They had to weld on a bolt on flange one end. $350 installed and the sensors I bought. 5 guys in the waiting area and 3 of them were in for the same thing. Such a shame.
Check engine light cleared at muffler shop. Noticed light was back on later that day after wife was driving. Getting codes later today to see what pops up.
