You do not want to drop $300 - $700 for a converter that breaks right away.

Your best bet may be to pick up a used one. If you look nearby, you might be able to get the entire assembly cheaply from someone who is parting out their car and you wont need to weld anything. If you cant get one, people will ship you cut sections of them.

Best of luck.
That may be my best route, a used one from car getting parted out.
There's really no change in performance, it's just annoying to see the CEL.

This used to be my daughter's car in Atlanta where there is emission testing.
I may have to register it here in Leesburg where there is no emission testing.

I just need to find a used cat.
The O2 sensors have never been changed and the car now has 237k miles.
Do you think a new O2 sensor might clear the code?
I am quite sure a new O2 sensor will read better and might trigger the same code. LOL.
