Default P0420 Catalyst System efficiency Below Threshold

Hey Guys,

I got the P0420 code, was able to clear the engine light, I have driven it for 2 days and it hasn't come back yet. I have my exhaust system checked by the muffler shop. The guys there tell me, they can hear rattling in Catalytic converter and there is leak by the flange and I need to replace CAT and front pipe.

They have quoted me with Walker after market part for @ $750. If I go with the OEM CAT, the parts alone would be $1300, by the time I'm done, it would be some where around 1600 bucks.

Is it okay to use after market parts? I have heard the check engine light comes back with after market parts as they are not of the high emissions standard. MY car needs California standard converter.

4 Cylinder, 2.2, Camry 2000

Is the car registered in California?

Is this the front cat?

It's registered in NY, the CAT is underneath the car.

Is walker NY compatible? Non OEM Cat okay to use? The OEM is twice the cost of after market.

The reason the Toyota part is so expensive is that the converter is not sold by itself (like the Walker) but comes with exhaust system.

California is the only state requiring "approved" emission parts. Get the Walker.
