Description

Part #: 51333

Keep the check engine light off with MagnaFlow OEM Grade Federal/EPA Compliant Direct-Fit Catalytic Converter 51333. 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 to fit the 2000-2005 Buick LeSabre, 2000-2005 Buick Park Avenue, and additional vehicles. Avoid potential exhaust leaks by using the included gaskets to get a proper seal. 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.

  • Your trusted source for EPA-compliant catalytic converters, providing assurance of genuine compliance while delivering quality that will last
  • High strength 16 gauge 409 stainless steel tubing for exceptional corrosion resistance and maximum service life
  • Expertly crafted to replicate OEM-like flow dynamics, maintaining factory performance and fuel efficiency
