Buick LeSabre Catalytic Converter - Direct Fit - Magnaflow - CARB Compliant - 2000. A California-grade direct-fit catalytic converter engineered to replace the factory unit on the 2000 Buick LeSabre while meeting CARB emissions requirements for listed vehicles.
This MagnaFlow converter (part number 4481204) is built to replicate OEM flow dynamics and maintain factory performance and fuel efficiency. The spun-body design with a single laser fusion weld minimizes leak points, while mandrel-bent tubing and corrosion-resistant 16 gauge 409 stainless steel construction provide long service life. As a direct-fit unit, it installs without cutting or welding when the correct tools and procedures are used and ships with the gaskets and hardware needed for a proper seal. It has undergone testing to comply with CARB guidelines for the listed applications; installation in CARB jurisdictions is permitted only if the converter’s CARB Executive Order includes the vehicle’s EO and Engine Family Number.
