Magnaflow 557404 California Grade CARB Compliant Universal Catalytic Converter - 2.00in

The MagnaFlow 557404 is a California Grade, CARB-compliant universal catalytic converter featuring a 2-inch inlet and outlet diameter. Engineered to meet or exceed California Air Resources Board (CARB) emissions standards, this converter carries Executive Order #D-193-133 and is legal for use in California and all other CARB-regulated states. Its universal design allows flexible placement and orientation to suit a wide range of exhaust system configurations.

Built with a clam-shell stainless steel body and ceramic honeycomb substrate, the 557404 delivers reliable emissions reduction while resisting the heat and corrosion demands of daily driving. A ribbed body design minimizes thermal expansion and distortion, keeping the ceramic catalyst properly aligned during operation. An integrated OEM-style heat shield adds an additional layer of thermal protection and structural rigidity.
