MagnaFlow OEM Grade Catalytic Converter — Chevrolet Express 3500 Passenger Side (`03-`07). A direct-fit, federal-compliant replacement designed to restore proper emissions control and help prevent check engine light issues for compatible trucks.
This passenger-side catalytic converter is engineered as an OEM-grade direct-fit for 2003–2007 Chevrolet Express 3500 models (verify fitment for 2500 or other variants before ordering). Manufactured with mandrel-bent tubing and stainless-steel construction, it’s built to mirror OEM flow dynamics while resisting corrosion. Designed using precise 3D scanning and metrology, the unit installs without cutting or welding and includes gaskets and hardware to reduce the chance of exhaust leaks. Torca AccuSeal-style clamping and OE-sized hangers maintain serviceability and alignment for long-term use.
