Description

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. It's built to replicate OEM flow dynamics and maintain factory performance and fuel efficiency. Features a spun-body design with a single laser fusion weld to minimize leak points, mandrel-bent tubing, and corrosion-resistant 16 gauge 409 stainless steel construction for long service life. It installs without cutting or welding and ships with gaskets and hardware.
