Product Details

The MagnaFlow 280543 is an OEM Grade, direct-fit replacement catalytic converter engineered to deliver factory-level performance and long-term emissions compliance. Designed as a precise bolt-on replacement, this converter installs without cutting or welding, making it suitable for DIY installation with standard hand tools.

MagnaFlow's OEM Grade designation means this converter is loaded with elevated levels of precious metals, engineered to satisfy the vehicle's computer control monitoring system (PCM/OBD-II) and keep the check engine light off. The enhanced precious metal loading also ensures proper engine management interaction and reliable emissions conversion even on vehicles not running at peak efficiency.

Key Features:

  • OEM Grade Construction – Elevated precious metal loading meets Engine Family Number-specific requirements for full OBD-II system compliance
  • Direct-Fit Design – Bolt-on replacement requires no cutting, welding, or custom fabrication
  • Stainless Steel Construction – Corrosion-resistant stainless steel body and tubing for superior longevity
  • Mandrel-Bent Tubing – Free-flowing mandrel-bent pipes eliminate exhaust restrictions and maintain optimal flow
  • CNC Precision Manufacturing – Robotic CNC manufacturing techniques ensure consistently perfect fitment
  • 3D Scan Verified Fit – State-of-the-art 3D scanning technology used during R&D to replicate OE fit and function exactly
  • Hardware Included – Necessary gaskets and mounting hardware included to simplify installation
  • Federal/EPA Compliant – Meets Federal EPA emissions requirements for OBD-II federally registered vehicles

Warranty: Backed by MagnaFlow's 5-year / 50,000-mile limited construction warranty and a 25,000-mile emissions warranty for worry-free ownership.

Emissions Compliance Notice: This is a Federal/EPA compliant catalytic converter. It is not legal for sale, installation, or use in the states of California, Colorado, or New York.
