need come help with a code

I've been getting the code 2C7E (Lambda probe behind catalytic converter) since I removed my VRSF downpipes.

I took it to the dealer last week and they replaced one of the o2 sensors.

Today the check engine light came back on for 2C7E, I believe they may have replaced the wrong o2 sensor. Does this seem likely?

Recently I was getting the code 2C7F (Lambda probe behind catalytic converter 2) and replaced the driver's side rear o2 sensor due to frayed wires. The code went away and has not come back.
