Magnaflow Catalytic Converter Direct Fit 02-06 Cooper S

Direct-fit catalytic converter for 2002–2006 Cooper S models that keeps the check engine light off by meeting California Grade CARB compliance and providing reliable emissions control.

This MagnaFlow Conv DF 02-06 Cooper/S Manifold (part number 452859) is engineered as a direct-fit replacement to restore emissions system integrity while maintaining exhaust flow characteristics compatible with performance exhaust and turbo upgrade applications.

• California Grade CARB Compliant: Ensures the converter meets required emissions standards to prevent diagnostic trouble codes and maintain legal operation in regulated areas.
• Direct-fit design: Simplifies installation by matching factory mating surfaces and mounting points for a precise, repeatable fit without modification.
• Free-flowing mandrel-bent tubing: Preserves exhaust gas velocity and minimizes internal restriction for a high-flow path through the converter.
• Highly corrosion resistant stainless steel construction: Reduces long-term corrosion risk in the exhaust system, supporting consistent performance and durability.
• Spun body converter: Provides a uniform shell geometry that aids fitment and structural integrity under thermal cycling.
• MagnaFlow brand engineering: Designed and manufactured by MagnaFlow to integrate with performance-oriented exhaust systems while prioritizing emissions compliance.

Installation is intended to be user-serviceable; the direct-fit form factor and factory-compatible connections allow this unit to be installed without specialty fabrication when using the proper tools and hardware.
