Nissan Quest Catalytic Converter - MagnaFlow (California Grade CARB Compliant, 2004). A direct-fit replacement (MagnaFlow part 5481296) engineered to restore emissions control and keep your 2004 Nissan Quest running within CARB-regulated limits.
This MagnaFlow converter features an OE-replicated spun body and mandrel-bent tubing to maintain factory flow dynamics and thermal efficiency. Constructed from high-strength 16-gauge 409 stainless steel and finished with a single laser fusion weld, it resists corrosion while reducing potential leak points. The unit ships with the required gaskets and hardware to simplify installation without reusing corroded factory pieces. It is designed specifically for the 2004 Nissan Quest and interchanges with OE part numbers 208A1-7Y100 and 208A1-8Y000. Intended for legal use where CARB-compliant parts are required; installation in CARB states requires matching Executive Order (EO) and Engine Family Number (EFN) per the converter’s CARB documentation.
