I had a question about your thoughts of an OEM replacement versus a Walker or other high quality, non-CARB replacement.

First, are non-OEM catalytic converters as "clean" as the OEM option in terms of emissions? I can't find any studies or data on this.

Second, do you see long-term negative effects on the car by using a non-OEM catalytic converter?

I live outside of California and went with a non-OEM Walker converter. I also installed a CatShield (I wish I'd done it sooner). The non-OEM part saved me at least $1,000 and I have a 2007 Touring Prius. I hope that was the right call!
