says it is most likely second catalytic converter. I'm thinking of just replacing both while he is in there. Have 169K on it so kill two birds with one stone. Have seen various manufacturers of this combo running from $430 to around $480. What have you guys done for yours when needed?

 

Have you checked the codes?

 

Yes, codes indicated second converter.

 

Do you have a 2GS300 or 2GS400? I haven't had to replace my cats yet and I'm at 224k....I'm in NC. What code did it give you?

 

2003 GS300. I don't know exact code.
