Well, I have to say, it works! This Prius Catalytic Converter Replacement saved someone I know hundreds of dollars if not thousands of dollars.
Well ill say this, no check engine lights, and all sounds and drives as expected!
I also ran the test of systems using the techstream and all are clean! The cost was a few hundred dollars, I hear PriusOverlanding.com has some as well. I used an OLD O2 sensor I had laying around and didn’t even disconnect the battery, only simply clear all codes with the tech stream.
