Magnaflow Catalytic Converter DirectFit 2004 Ford F150 5.4L

Magnaflow Catalytic Converter DirectFit 2004 Ford F150 5.4L ensures emissions compliance and keeps the check engine light off while providing reliable, direct-replacement performance for the 5.4L F150.

Engineered by MagnaFlow, this California Grade CARB-compliant direct-fit converter (part number 5582705) is designed for straightforward installation and consistent emissions control.

Key technical features and why they matter

• California Grade CARB compliant: Maintains required emissions standards for CARB-regulated markets, helping prevent emissions-related faults.
• Direct-fit design (no cutting or welding): Simplifies installation by matching factory mounting points and flanges, reducing labor time and the need for modification.
• Mandrel-bent tubing: Minimizes internal flow restrictions to support smoother exhaust flow and reduce backpressure compared with restrictive bends.
• Stainless steel construction: Provides corrosion resistance and long-term durability in under-vehicle environments, supporting consistent performance over time.
• Part number 5582705: Factory-referenced identifier for accurate ordering and fitment verification.

This converter's combination of mandrel-bent tubing and corrosion-resistant construction supports a high-flow replacement path within a performance exhaust system, while preserving stock fitment and emission control characteristics. The direct-fit approach makes it suitable for DIY installation when the proper tools are available, without the need for cutting or welding.

Installation and use

Installation is intended to be straightforward for technicians or experienced DIYers: direct-fit mounting replaces the factory unit using existing hangers and flange locations. Proper tools are required to ensure secure sealing at the mating flanges and vehicle electrical connections for oxygen sensors remain properly retained to avoid diagnostic faults.

Brand background: Magnaflow is known for engineered exhaust and emissions components designed for durability and predictable performance in both street and motorsports-influenced applications.
