"This cat was for my 2001 chevy impala, it fit well, no engine check lights came on, and gave a small boost in performance. This product was cheaper than oem, and I am glad I decided to go with the aftermarket part once I saw how restrictive the oem was. This product was mandrel bent and had larger pipes than oem. Great deal for the money." —Mark L from Southampton, PA bought a Magnaflow Catalytic Converters - 49 State Legal for a 2001 Chevy Impala, 3.4L V6, code E engine.
