Cadillac DeVille Catalytic Converter - Magnaflow - Direct-Fit - `00-`05 is an OEM-grade replacement designed to restore proper emissions control and help keep the check engine light off. This direct-fit converter is made for 2000–2005 Cadillac DeVille applications and installs without cutting or welding when proper tools are used.
Built to meet Federal/EPA emissions requirements for OBDII federally registered vehicles, this MagnaFlow unit replicates OE fit and flow characteristics. The spun-body design with a single laser fusion weld reduces leak potential while the compact, low-mass construction promotes thermal efficiency. MagnaFlow’s R&D uses precise metrology to match OE dimensions so the part fits and functions like the original. The converter ships with the necessary gaskets and hardware for a proper seal and straightforward installation. Note: Not legal for sale or installation in California, Colorado, or New York.
