Chevrolet Silverado 2500 Performance Exhaust - Magnaflow - Direct-Fit Catalytic Converter - `03-`06 is a MagnaFlow California-grade, CARB-compliant direct-fit catalytic converter designed for 2003–2006 Silverado 2500 HD trucks. It replaces the factory converter with OE-like fit and flow while maintaining emissions compliance.
This direct-fit converter features mandrel-bent tubing and corrosion-resistant stainless steel construction for durable, free-flowing exhaust performance without cutting or welding. MagnaFlow’s R&D uses 3D scanning to replicate OE spun-body geometry, and a single laser-fusion weld reduces leak potential. The compact, low-mass design improves thermal efficiency and the included gaskets, hardware, and Torca AccuSeal® clamps help ensure a proper seal and serviceability. Designed to fit 2003–2006 Chevrolet Silverado 2500 HD and compatible GMC Sierra 2500 HD applications, this unit is supplied to meet CARB requirements where applicable; installation is permitted only if the converter’s CARB Executive Order (EO) and Engine Family Number (EFN) apply to the vehicle.
