OBD Code P0432 (1/2 Catalytic Converter Efficiency)

[Daveh370]

No luck with the new O2 sensors; CEL came back on and got same P0432 code. Guess I’ll be ordering new pre cats/midpipe.

That would be my next step as well.

Chris, any recommendations on the downpipes/midpipe/pre-cats?

Are those stainless or mild steel?

Are they noticeably better than these?

It's been so long I can't recall.

All I know is that you're not going to gain anything from going with one versus the other. Well, unless one of them is stainless versus aluminum, or something like that.

But in terms of anything else, they're just cats. I'd just go with whatever is cheapest.
