MagnaFlow 456056 Catalytic Converter - Left or Right

California OBDII Catalytic Converter

MagnaFlow 456056 is a California Grade, CARB-compliant universal catalytic converter built for OBDII-equipped vehicles that require a 2.50-inch weld-on replacement. Its stainless steel spun-body construction, ceramic substrate, and compact low-mass design are intended to support corrosion resistance and thermal efficiency while helping keep the check engine light off.

This MagnaFlow California OBDII Catalytic Converter line is engineered for vehicles that must meet California Air Resources Board requirements. For listed applications such as the 2005-2006 Chrysler 300, 2005-2006 Dodge Charger, 2005-2006 Dodge Magnum, and 2003-2004 Dodge Neon, it provides a CARB Executive Order-approved replacement path when the vehicle-specific installation requirements are followed.

What It Helps Address

• Check engine light concerns related to catalytic converter efficiency
• Failed emissions testing on CARB-regulated vehicles
• Corrosion issues in exhaust replacement service
• Leak concerns at the converter body from welded construction
• Replacement needs for OE-spec exhaust repair on Chrysler, Dodge, and Neon applications

Installation Notes

Installation requires cutting and welding, so the converter must be positioned and secured by an experienced exhaust technician. Verify the vehicle’s engine family and CARB Executive Order requirements before installation, and confirm the 2.50-inch inlet and outlet dimensions, sensor port location, and listed left, right, or N/A application details for the exact vehicle.

Because this is a universal weld-on converter, fitment depends on the listed application and proper exhaust fabrication. MagnaFlow 456056 should be matched to the correct vehicle configuration before final welding.

Quality Assurance

MagnaFlow 456056 is built to meet or exceed California Air Resources Board requirements and has undergone additional testing for CARB guideline compliance on the listed vehicles. The stainless steel construction, spun body design, and laser fusion weld are used to support durability and sealing performance in emissions service.
