Chevrolet Express 2500 Catalytic Converter - Passenger Side - Magnaflow - HM Grade Direct-Fit - 03-05. A direct-fit replacement catalytic converter built to match OEM fitment and designed to meet Federal/EPA emissions requirements for compatible OBDII vehicles.
This MagnaFlow HM Grade unit is engineered for straightforward installation and reliable service. Mandrel-bent tubing maintains smooth exhaust flow while stainless steel construction resists corrosion. The part is developed using 3D scanning and metrology to replicate original geometry, minimizing fitment headaches. Included gaskets and hardware reduce the chance of exhaust leaks and avoid reusing corroded factory parts. Proper installation with common tools requires no cutting or welding and helps keep the check engine light off when installed correctly.
