2003 Lexus RX300 Question: MY RX 300 2003 engine light with vsc

I replaced o2 sensor one year back.now they said rear side sensor gone and 2 sensor will cost $500.00,also i have to change my engine pipe which cost 300 bucks. Is it real price? -
Answer 1
do you mean the front engine connector pipe with the flex joint? -
Answer 2
you did not tell us the full story. sometimes, you can't remove the old oxygen sensor (age, rust, moon phases) and the pipe that it screws into has to be replaced. if this is what happened, they are correct. -
