Product Information

Product Details
Part No. 51257
Warranty Details (5 YR REPLACEMENT IF DEFECTIVE)
Keep the check engine light off with MagnaFlow OEM Grade Federal/EPA Compliant Direct-Fit Catalytic Converter 51257. With features including free-flowing mandrel-bent tubing and highly corrosion resistant stainless steel construction, easily install this spun body converter yourself using the proper tools, no cutting or welding required. MagnaFlow's state-of-the-art metrology department uses the latest 3D scanning systems during research and development, so you can be confident that your new part will fit and function like the original equipment. By replicating the OE spun body design, the single laser fusion weld greatly reduces the possibility of a leak, and our compact, low-mass design also allows for greater thermal efficiency. This direct-fit catalytic converter is designed specifically for the 2003-2006 Hyundai Santa Fe and interchanges with OE parts 28530-39911 and 28530-39930. The included gaskets & hardware reduce the possibility of a leaking seal while avoiding the need to reuse corroded factory parts for installation. This replacement part is designed to meet or exceed Federal emissions requirements set forth by the EPA, complying with legal standards for OBDII Federally registered vehicles with California or Federal/EPA Emission systems.

Product Features:
  • Expertly crafted to replicate OEM-like flow dynamics, maintaining factory performance and fuel efficiency.
  • Simplifies installation with essential gaskets and hardware being included in the box.
  • Your trusted source for EPA-compliant catalytic converters, providing assurance of genuine compliance while delivering quality that will last.
