Recommendations on Catalytic Converter manufacturer

Post by cyg » Tue Apr 17, 2018 9:13 am

The P420 code CEL code has been off and on for a while (more off than on), so I am finally getting around to fixing it.

As of right now my '13 PI with Eco is at 165k miles. The two options I have for aftermarket catalytic converters are Davico and DEC (OEM is literally more than twice the cost). Anyone have any recommendations?

Stick with OEM or a 50-state legal high quality cat if you want the CEL to stay off. If you cheap out the cat won't last as long, they're cheaper for a reason.

Since your issue is intermittent you could try a can of cataclean - https://amzn.to/2vmBjqC - it may help for a while if the cat isn't truly damaged internally. It's more likely to work if you haven't been driving with the code set for a while.

With that said, before spending any money on parts, you should use a scan tool to watch all of the O2 sensor readings in real time. Most likely your cat is not operating at peak efficiency anymore but at least you can confirm that. Be aware that cats really don't go bad, they are usually killed by misfires, coolant getting through the engine (head gasket, etc.).

I will try the cataclean and see how that goes.

I posted this last year right after I had a GDI cleaning done that explains the situation - I was getting misfires and had a fouled O2 sensor.

Both DEC and Davico are the only non-OEM manufacturers of cats for my that meet the EPA guidelines (there isn't a manufacturer that makes a cat for all 50 states as NY and CA have different guidelines), so I am not sure what constitutes a high quality cat between those two as from what I can tell DEC has a better build and Davico has a better catalyst.

You're better off getting an OEM cat for best results. Or buy a california cat as a second choice. My $.02.
