Product Details

This MagnaFlow HM Grade manifold converter is built for drivers needing a direct replacement for the factory exhaust manifold with integrated catalytic converter on the Hyundai Santa Fe. Part number 50335 is formed to replicate the original spun-body OE style, and MagnaFlow’s 3D scanning-based development process helps ensure proper fitment and alignment. The stainless steel construction and single laser fusion weld are used to support durability and reduce the chance of exhaust leaks.

This part cross-references OE numbers 28510-37300 and 28510-37430 for the same application. It is a Federal/EPA compliant replacement for vehicles equipped with Federal emissions systems, and it is not for California applications.

Common Repair Applications

• Check engine light related to catalytic converter efficiency
• Failed emissions inspection due to converter performance
• Exhaust leaks at the manifold or converter assembly
• Corroded or damaged factory exhaust manifold converter
• Replacement of worn OE part 50335-style manifold converter assembly

Installation Notes

Install using the proper tools and follow the vehicle-specific service procedure. This direct-fit unit is designed for bolt-on installation with no cutting or welding required. Included gaskets and hardware help reduce the chance of a leaking seal and eliminate the need to reuse corroded factory fasteners.

Verify your Santa Fe’s emissions configuration before ordering. This MagnaFlow 50335 is for 2001-2006 Hyundai Santa Fe applications with Federal/EPA emissions equipment, including the listed rear-position fitments.

Quality Assurance

MagnaFlow uses 3D scanning and metrology during product development to match OE dimensions and function. The HM Grade Federal/EPA Compliant line is engineered to meet or exceed Federal emissions requirements for properly equipped OBDII vehicles.
