To be honest, I discovered it is illegal to use these devices, as I intended. Parts are excellent

Saved my life had to get back to work.
Fixed my catalytic converter code make sure you put it on the one towards the rear of your car not the one before the cat or on the cat the one after the cat is the one you want. You only need one so you can save the other for your other car in the future. Passed my inspection great value for the money.🙏 take off 02 sensor install this and then the 02 or both together. Then replug in 02 sensor connector.

Did the trick
Got it to help eliminate a P0420 (cat converter code) on my 2008 prius and it worked after doing a bit of modification to it. In general if you have an old vehicle and you don't want to spent hundreds of dollars to get a new Catalist system this should do the trick. Use at your own risk, it worked for me, may or may not work for you.
