Customer Review: (see review/s)
  • I ordered this catalytic converter for my 4runner. I had it professionally installed. Within days, my check engine light came on. This part was defective from the start. I am extremely inconvenienced because even though it is under warranty, I will have to pay another $300 for the new one to get installed since labor is not included in the warranty. I will never purchase this part again!
