California Grade Direct-Fit Converter

MagnaFlow 452021 is a CARB-compliant direct-fit catalytic converter with integrated exhaust manifold design for select Hyundai and Kia applications. It is built for a bolt-on installation and uses stainless steel construction, ceramic substrate material, and OE-style fitment to help keep the check engine light off.

This MagnaFlow California Converters part line is engineered for emissions-controlled vehicles that require a direct replacement with factory-style geometry. The spun body design, mandrel-bent tubing, and laser fusion weld construction are used to support thermal efficiency and reduce leak points. MagnaFlow 452021 also cross-references OE part numbers 28510-37381 and 28510-37162 for the same application.

  • Corrosion damage to the original exhaust manifold and converter assembly
  • Exhaust leaks at worn factory sealing surfaces
  • Fitment issues from using a non-direct replacement part

Installation Notes

Install with the proper tools using the bolt-on connections; cutting or welding is not required. The included gaskets and hardware help reduce the chance of a leaking seal and eliminate the need to reuse corroded factory fasteners. Verify oxygen sensor placement and confirm vehicle emissions certification before installation on a 1999-2006 Hyundai Sonata, Hyundai Tiburon, or Kia Optima.
