MagnaFlow 441404 Catalytic Converter - Rear, Rear Left or Rear Right

California-Grade Universal Catalytic Converter

MagnaFlow 441404 is a California Grade, CARB-compliant universal catalytic converter built for select Ford and Saturn applications that require a 2-inch inlet and outlet. Its stainless steel construction, ceramic substrate, and oval clam-shell body are designed for durable exhaust service while helping keep the check engine light off on listed vehicles.

The MagnaFlow California OBDII Catalytic Converter line is built for vehicles that need emissions-compliant replacement coverage in California and other CARB-restricted states. Part number 441404 follows that product line approach with a universal weld-on design for applications where cutting and welding are part of the installation.

What It Helps Address

• Check engine light concerns related to catalytic converter efficiency

• Corrosion-related converter replacement in underbody exhaust service
• Need for a weld-in, CARB-listed universal converter solution

Installation Notes

Installation requires cutting and welding. This converter uses weld-on inlet and outlet connections, straight inlet and outlet orientation, and no oxygen sensor ports. Verify the vehicle’s engine family, emissions certification, and rear-position application before installation. Because this is a universal design, proper exhaust alignment and professional welding are important for a correct seal and fit.
