Review on Catalytic Converter Compatible Convertor Direct Fit Replacement Parts in Exhaust & Emissions by Fred Whitehead

Looked like it worked right out of the box. Honda Accord 2006 4 cylinder. Check the engine light for code P0420, which indicates a bad catalytic converter. Reset the light and it will come back a few miles later with the same code. bad detail. Contacted the seller and was asked to request a replacement. The replacement came a few days later. I installed a new part, reset the code and drove about 20 miles before the check engine light came on again with the same code, P0430. I drove another 100 miles and reset the code multiple times only for it to come back. There are no other codes and the car has been tuned for the last 1000 miles. There are no problems other than code P0420. I will contact the seller again to find a solution.
