MagnaFlow California Direct-Fit Catalytic Converter 4481699 for 2003 Cadillac CTS is a CARB-compliant replacement designed to restore emissions control while maintaining OEM fitment. This direct-fit unit installs without cutting or welding and includes the gaskets and hardware needed for a proper seal.
Engineered using MagnaFlow’s 3D-scanning R&D and OE-spun body replication, this converter uses mandrel-bent tubing and a compact, low-mass design to preserve factory flow dynamics and thermal performance. The single laser fusion weld minimizes leak points, and corrosion-resistant materials improve service life. It’s made to simplify swapping a worn or damaged converter while keeping emissions systems functioning and avoiding reuse of corroded factory parts.
