MagnaFlow Cat Converter Direct Fit EPA 2018 BMW 530e

Restores emissions control with the MagnaFlow 18-22 BMW 530e OEM Grade Federal / EPA Compliant Direct-Fit Catalytic Converter, keeping the check engine light off and maintaining regulatory compliance for reliable day-to-day operation.

Built by MagnaFlow to OEM-grade standards, this direct-fit catalytic converter (part number 280544) is designed for like-for-like replacement on compatible BMW 530e models. The unit focuses on durability, flow efficiency, and simple installation to preserve factory performance and emissions behavior.

• OEM Grade Federal / EPA Compliant converter — Ensures the vehicle meets federal and EPA emissions requirements, which directly addresses emissions monitoring and helps prevent diagnostic trouble codes related to catalyst performance.
• Direct-fit design — Preserves factory mounting points and dimensions for a straightforward replacement that maintains factory exhaust geometry and fitment integrity.
• Free-flowing mandrel-bent tubing — Reduces flow restriction compared to crushed bends, helping maintain exhaust scavenging characteristics and preventing backpressure-related performance loss.
• Highly corrosion resistant stainless steel construction — Improves long-term durability against road salts and corrosion, extending service life in real-world conditions.
• Spun body converter — Provides a robust formed housing that resists deformation while maintaining consistent internal clearances for stable catalytic function.
• Part number 280544 — Factory-referencing identifier for ordering and verification against vehicle requirements.
• User-installable form factor — Designed for straightforward replacement without modification to the exhaust system when using appropriate installation procedures and hardware.

Why this matters: each feature targets the core needs of emissions control and vehicle reliability. The EPA-compliant catalyst restores regulated conversion efficiency, the mandrel-bent tubing and direct-fit layout preserve exhaust flow and factory dynamics, and stainless construction with a spun body housing reduces the likelihood of premature corrosion or mechanical failure.

Performance-focused installers and technicians will value the combination of proven brand engineering from MagnaFlow and a replacement part that prioritizes functionality and compliance over unnecessary complexity.
