I have not installed the products yet but they do seem to match up side by side with the old cats that fell off the car. Also the quality looks good.

This unit solved my issue in passing the California Smog Test... A 1992 5.7L is as clean as any new car today! (HC= 14/7, CO=0.03/0.02; NO=299/34) WOW! I should have replaced my old Catalytic Converter & O2 Sensor units first and stop worrying about the test results.
