MagnaFlow 5451831 California CARB Compliant Direct-Fit Catalytic Converter

The MagnaFlow 5451831 is a California Grade CARB compliant direct-fit catalytic converter engineered as a precision replacement for the original equipment converter. Designed to keep the check engine light off and restore proper emissions performance, this bolt-on replacement installs with basic hand tools — no cutting or welding required.

Key Features:

• CARB Compliant: Meets or exceeds California Air Resources Board (CARB) requirements and is legal for use in California and all other CARB-restricted states for applicable vehicles
• Direct-Fit Design: Replicates the OE spun body design for a precise, bolt-on installation without modifications
• Mandrel-Bent Tubing: Free-flowing mandrel-bent tubing eliminates exhaust flow restrictions for optimal engine performance
• Stainless Steel Construction: Highly corrosion-resistant stainless steel body and tubes provide long-lasting durability
• Laser Fusion Weld: Single laser fusion weld on the spun body design minimizes the risk of exhaust leaks
• Compact, Low-Mass Design: Allows for greater thermal efficiency compared to heavier alternatives
• 3D Scan-Verified Fitment: Developed using MagnaFlow's state-of-the-art metrology department and 3D scanning systems to ensure OE-accurate fit and function
• Ceramic Substrate: High-cell-count ceramic substrate delivers efficient emissions conversion

This catalytic converter has undergone additional emissions testing to comply with California Air Resources Board (CARB) guidelines, making it the correct choice for vehicles registered in California, Colorado, New York, and other CARB-regulated states. It is a direct replacement that restores factory-level emissions compliance and exhaust system integrity.
