OEM vs. Aftermarket Catalytic Converters
Read several threads about Cats and mods but what I would like to know is if an aftermarket Cat like the Walker Direct-Fit Converter 73013 & 73014 would be a good fit for my 2010 V6 LT RS Camaro? Had a reman engine put in through dealer (I know should have went with the V8) because the engine that was in it was tore up (Not from me). Threw code P0403 and they said it was a bad Cat. The OEM is 1050.00 alone not counting labor, (I can get both right and left cats in the Walker listed above and sensors with install for 1400.00 at a non-dealer shop). I called a few shops both suggested the Walker but the dealer said that aftermarkets dont live long...I was like new engine new converter should be no problems right? I asked if they tested the downstream O2 sensor and they offered no solid response other than you need the Cat.
All i would like to know is what experiences have any of you had with aftermarket Cats and any recommendations you may have. I know it sounds crazy but I want to keep it as close to stock as I dont have a shop to lift it and do the work myself. Will an aftermarket Walker and new O2 sensors work fine? Any help is appreciated. |

The walkers are $250 a piece. If you have basic tools and jack stands you can replace it your self and save some money.

I got aftermarket, and a P0430 code... I had P0420 and P0430, but after the
down-pipes with cats were replaced, the P0430 remained. They told me they are high-flow cats, which the car does not like. I am working on the issue, and the spark plug anti-fouler did not help. When in doubt, buy the CARB appoved ones, they're dipped a few more times... |

My Sierra threw P0430 a cpl times. Now it’s fine. So idk what threw it? Maybe shitty gas?
