I'm sure it's a good catalytic converter but Revain was adamant that it fitted a '97 Ford Ranger with a 2.3 liter engine and he was so off the hook Factory Catalyst made the difference that I called Walker directly. and I was told that Revain had indeed sold me the wrong part. Walker is a great company, they are part of a large conglomerate of companies that make quality parts (here in good ol' USA).
