Review on Walker 16467 Direct Catalytic Converter by Stephen Johnson

2 years later and no problem. At the same time I also replaced the secondary cats with another brand. I followed the breakage procedure in the procedures that came with the other brand to keep the catalyst from coming loose. Guess what? Another brand had its catalytic converter fall off after two years, but these, which went through the break-in procedure with no warning, are still holding up.
