I bought your CEL eliminator 04/13/2013. I had called and asked if this product would work on my 2005 Scion tC. You said that it works 100% of the time (as long as there are no emissions codes before removing the converter & it is the screw in type) on American gas cars and trucks but couldn't be certain on a Scion. I just wanted to let you know that I did install this on my car and I haven't had the CEL light come on yet. I have put a little over 400 miles on it. I took the car to the local mechanic on 4/25/2013 and asked him to hook up his emissions scanner to the OBD II. He ran all the tests and said everything was set at ready and passed his test so I should have no problems running the car through emissions testing. Also as a side note, I have already noticed a huge difference in my gas mileage. I'm going to say it has improved at least by around 30%.I want to thank you for this product. It is a great inexpensive temporary fix until a new catalytic convertor can be purchased and installed.
