Mazda B3000 Catalytic Converter - Rear - MagnaFlow - HM Grade Direct-Fit - `04-`06. This direct-fit rear catalytic converter replaces the OE unit and is designed to keep your emissions system functioning to Federal/EPA standards while maintaining factory flow characteristics.
Built to MagnaFlow's HM Grade specifications, this converter uses a spun-body design and precise 3D-scanned fitment to match the original equipment geometry for the 2004–2006 Mazda B3000. The compact, low-mass design helps thermal efficiency and the single laser fusion weld reduces potential leak points. It ships with the necessary gaskets and hardware for a straightforward direct-fit installation with no cutting or welding required when the correct tools are used.
