Magnaflow 5531081 California Manifold Catalytic Converter

The MagnaFlow 5531081 is a direct-fit manifold catalytic converter designed to meet California Air Resources Board (CARB) emissions standards. This unit combines the exhaust manifold and catalytic converter into a single, integrated assembly, simplifying installation and reducing the number of potential leak points in the exhaust system.

MagnaFlow engineers this converter to deliver reliable emissions compliance without sacrificing exhaust flow performance. The close-coupled manifold design positions the catalyst near the engine for faster light-off times, meaning the converter reaches optimal operating temperature more quickly—resulting in better emissions control from cold starts.

Key Features:

• California Air Resources Board (CARB) compliant — legal for sale and use in California and all 50 states
• Integrated manifold and catalytic converter design for simplified installation
• Close-coupled catalyst placement for rapid light-off and improved cold-start emissions performance
• High-cell-count substrate for superior catalytic efficiency and exhaust flow
• Direct-fit replacement engineered to OEM specifications for precise fitment
• Stainless steel construction for long-lasting corrosion and heat resistance
• Pre-installed oxygen sensor port(s) for hassle-free sensor transfer

As a direct OEM-style replacement, the MagnaFlow 5531081 installs using factory mounting points and hardware, minimizing downtime and the need for custom fabrication. MagnaFlow is an ISO 9001-certified manufacturer and a leading name in aftermarket exhaust and emissions products.
