Hello guys, I need your help and opinion about this check engine light and P0420 code. It’s catalytic converter on exhaust manifold. There is lot of them for purchase on eBay and AutoZone or other retail stores. OEM is about 1100$. Do you have any idea which one will delete code or what I can do to fix this problem? If you have experience with aftermarket please share with me.

 

ebay vendors for car parts are a risk imo. you don't need an oem part; a part from a jobber is my choice Napa is one such. No autozone around me so can't speak for them
