Nissan Maxima Catalytic Converter - MagnaFlow - Direct Fit - 2004 is a MagnaFlow California Grade CARB-compliant direct-fit catalytic converter engineered for the 2004 Nissan Maxima. It replaces the factory unit with a spun-body, bolt-on design that simplifies replacement while maintaining proper emissions control.
This direct-fit MagnaFlow converter uses mandrel-bent tubing and corrosion-resistant stainless steel construction to retain OEM-like flow dynamics and thermal efficiency. The spun body and single laser fusion weld reduce potential leak points, and the compact, low-mass design helps the converter warm up efficiently. Installation is straightforward with the included gaskets and hardware — no cutting or welding required when installed with proper tools. This unit is designed to meet California Air Resources Board requirements; installation is permitted only if the vehicle’s CARB Executive Order (EO) and Engine Family Number (EFN) appear in this converter’s CARB Executive Order. Interchanges with OE part numbers 208A2-7Y10A and 208A2-7Y60A.
