Chevrolet Express 3500 Catalytic Converter - Passenger Side - MagnaFlow - HM Grade Direct-Fit - 2003-2005. This direct-fit MagnaFlow HM Grade catalytic converter is designed to replace the OE unit on the passenger side of 2003–2005 Chevrolet Express 3500 models and restore proper emissions control on federal/OBAII systems.
Built to meet federal EPA emissions requirements (HM Grade), this converter uses mandrel-bent tubing and durable stainless steel construction to replicate OEM flow characteristics and resist corrosion. MagnaFlow’s use of 3D metrology during design helps ensure a precise fit and proper alignment with existing exhaust hangers and flanges. The unit ships with gaskets and hardware to reduce the chance of leaks and simplifies installation for technicians or experienced DIYers—no cutting or welding required when replacing the direct-fit unit.
