    • Q:

      I have a Toyota highlander 2004 2.4L. it has a check engine light on and Vsc light on. I went advanced auto and they checked to find out that the catalyst efficiency below threshold B1 code P0420 They told me to buy a catalyst converter. I need to know if this this the right product for my car. I don't know if it has one catalytic converter or several of them. I went to my mechanic he told me the same thing using. So there is a universal converter and this catalytic converter .........what is the difference.

        Happy to help, Remmy! This Manifold converter is a direct fit for your Highlander, however there is also Walker exhaust 16364 converter which is needed. Please make sure which one you are going to replace.Universal converters are available too, however they have fitment issues and require modifications to fit properly, most of the times.
