Volkswagen Passat Catalytic Converter - Magnaflow - OEM Grade Direct-Fit - `06-`08. A direct-fit replacement engineered to match original equipment fit and flow for 2006–2008 Volkswagen Passat models, designed to restore proper emissions function and keep OBDII systems operating correctly.
This MagnaFlow OEM-grade converter (part 51799) uses a spun-body design and precision metrology-driven development to reproduce OE dimensions and flow characteristics. Built with high-strength stainless materials and mandrel-bent tubing, it minimizes pressure drop while resisting corrosion. The single laser fusion weld on the spun body reduces potential leak points and the compact, low-mass core supports thermal efficiency. Included gaskets and hardware reduce the need to reuse corroded factory seals, and Torca AccuSeal® clamps help maintain a reliable joint without pipe distortion. This unit interchanges with OE part numbers 3C0 254 504 BX and 3C0 254 502 TX; verify fitment against your VIN before purchase. Designed to meet or exceed Federal emissions requirements set forth by the EPA for federally registered OBDII vehicles—check local regulations for sale or installation restrictions in California, Colorado, or New York.
