I went to diagnosis my car because the check engine and the traction system light was on. Initially, I did it at Midas and they said it needs catalyst converter replacement costing $2400, when I checked with Lexus service center they said it needs Exhaust Y pipe which costs $3200. I am not quite sure what is going on, can someone help me.
There are secondary catalytic converters in the front (y-) pipe, if that's what you are confused about.
That said, they don't typically cause a CEL, as catalyst efficiency is based on the primary catalytic converters. Did Lexus actually diagnose the car as well?
Thank You for the reply. The diagnosis was done by Lexus service center and they said the catalytic converter and the Exhaust Y pipe needs to be replaced. Can you let me know what is the best option, my car is on 72 K miles now.
