MagnaFlow Catalytic Converter Direct Fit Rear BMW 325 330 Z3

Direct-fit catalytic converter (MagnaFlow Conv DF) that keeps the check engine light off by meeting California Grade CARB compliance while delivering reliable emissions control for compatible BMW applications.

This MagnaFlow California Grade CARB Compliant Direct-Fit Catalytic Converter (part number 452288) is engineered for functional durability and straightforward replacement in OE-style locations.

• California Grade CARB Compliant — ensures the converter meets California emissions standards, maintaining legal on-road operation and preventing emissions-related fault codes.
• Free-flowing mandrel-bent tubing — preserves internal diameter through bends to minimize flow restrictions and reduce exhaust backpressure compared to crushed or sharply bent tubing.
• Highly corrosion resistant stainless steel construction — provides long-term resistance to corrosion and environmental degradation, extending service life in road and climate exposure.
• Spun body converter — factory-formed body shape designed for structural integrity and consistent internal substrate placement; the design also supports straightforward direct-fit installation.
• Direct-fit design — engineered to match OE mounting points and flow orientation for simplified replacement without extensive modification.

Performance and serviceability focus: the combination of mandrel-bent tubing and corrosion-resistant stainless steel construction maintains exhaust flow characteristics and physical durability over time, while the direct-fit, spun-body layout reduces installation time and alignment steps.

Part number: 452288 — manufactured and supplied by MagnaFlow to the specifications indicated.

Installation note: the product description indicates the converter can be easily installed as a direct-fit spun body unit; follow standard vehicle service procedures and local regulations when replacing emissions components.
