Magnaflow Converter Direct Fit 3.3L 2004 Lexus ES330

Direct-fit catalytic converter designed for the 2004 Lexus ES330 3.3L — the Magnaflow Direct Fit Converter keeps the check engine light off while delivering reliable, high-flow emissions control and long-term corrosion resistance.

This MAGNAFLOW California Grade CARB Compliant Direct-Fit Catalytic Converter (part number 5571754) is engineered for like-for-like replacement with a focus on durability, flow, and straightforward installation.

• California Grade CARB Compliant — Ensures the converter meets stringent emissions standards required in CARB-regulated regions, preserving emissions control and legal compliance.
• Direct-fit design — Factory-matching geometry and inlet/outlet locations simplify replacement and reduce installation time compared with universal converters.
• Free-flowing mandrel-bent tubing — Mandrel bends maintain internal diameter through bends to minimize restriction, supporting a high-flow exhaust characteristic and stable backpressure for consistent engine operation.
• Highly corrosion-resistant stainless steel construction — Stainless materials provide long service life in corrosive environments, reducing the risk of premature failure from rust or corrosion.
• Spun body construction — A spun shell provides a compact, robust housing that resists vibration and improves mechanical integrity under road and thermal cycles.
• MagnaFlow brand engineering — Manufactured by Magnaflow, a recognized name in performance exhaust and emissions components, ensuring quality control and product traceability.

Functionally focused, this converter preserves emissions performance while offering the flow characteristics favored by performance exhaust applications, without altering the vehicle’s original exhaust routing. The unit is intended for straightforward installation and replacement on compatible vehicles, allowing owners to address emissions faults and maintain system integrity quickly.
