MagnaFlow 24204 Catalytic Converter

Direct-Fit Catalytic Converter for GM Sedans

MagnaFlow 24204 is a direct-fit HM Grade catalytic converter built for Federal/EPA-compliant OBDII vehicles outside California. It is engineered for a bolt-on replacement on select 2000-2005 Buick LeSabre, 2000-2005 Buick Park Avenue, and 2000-2005 Pontiac Bonneville applications.

The HM Grade Direct-Fit line focuses on OE-style fitment and straightforward replacement, using stainless steel construction, mandrel-bent tubing, and a spun-body design to match the original exhaust layout. The compact, low-mass design supports thermal efficiency, while the included gaskets help create a proper seal at installation.

Product Overview

MagnaFlow 24204 is designed as a direct replacement for the original catalytic converter on select Buick and Pontiac sedans. The HM Grade Direct-Fit series is built around OE-style dimensions and installation points, which helps reduce the need for fabrication during exhaust service. For shoppers searching for a catalytic converter for a 2000-2005 Buick LeSabre, a 2000-2005 Buick Park Avenue catalytic converter, or a 2000-2005 Pontiac Bonneville exhaust replacement, this part provides a vehicle-specific solution that aligns with Federal/EPA emissions requirements.

This part cross-references Walker (e.g., 16337, 16437) for the same application.

Common Repair Uses

• Replacing a failed or restricted catalytic converter
• Addressing exhaust leaks at the converter connection
• Restoring emissions-system function on Federal/EPA vehicles
• Resolving check engine light concerns related to converter efficiency
• Replacing a rusted or damaged OE-style exhaust component

Installation Notes

Installation is bolt-on at the inlet and clamp-on at the outlet, with no cutting or welding required when used on the listed applications. Use the included gasket to help achieve a proper seal and reduce the chance of exhaust leakage. Verify Federal/EPA emissions configuration before installation, since this part is not for California applications.

Quality Assurance

MagnaFlow uses 3D scanning and metrology during development to match OE fit and function. The spun-body construction and laser fusion weld are used to reduce leak potential and support consistent exhaust flow in the intended application.
