This product was more than I expected. Well built and added a detailed clean look to my exaust.

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.
