MagnaFlow 5411014 Catalytic Converter - Front

California OBDII Direct-Fit Converter

MagnaFlow 5411014 is a California Grade, CARB-compliant direct-fit catalytic converter built for front-position Subaru applications. It is engineered with stainless steel construction, a ceramic substrate, and bolt-on inlet and outlet connections for a direct replacement on listed vehicles.

Designed for the 2007-2016 Subaru Outback, Legacy, Impreza, and WRX STI front applications, MagnaFlow 5411014 uses OE-style spun body construction and mandrel-bent tubing to support proper exhaust flow and fitment. The compact design and laser fusion weld help reduce leak points, while the included gasket and mounting hardware support a cleaner installation.

Detailed Fitment and Function

This catalytic converter is built for front-position Subaru exhaust service where emissions performance, fitment accuracy, and legal compliance matter. It is a direct replacement for 2007 Subaru Outback front, 2007-2009 Subaru Legacy front, 2008-2014 Subaru Impreza front, and 2015-2016 Subaru WRX STI front applications. MagnaFlow 5411014 also cross-references OE part numbers 44102AG030 and 44102AG040 for the same application.

What It Helps Fix

• Check engine light caused by catalytic converter efficiency faults
• Failed emissions inspection on CARB-regulated Subaru vehicles
• Exhaust leaks at the converter body or flange connections
• Corrosion-related replacement needs on factory exhaust components
• Poor fitment from non-direct replacement exhaust parts

Installation Notes

Install using the proper tools and follow the vehicle-specific service procedure. This direct-fit design is made to install without cutting or welding on the listed Subaru applications. Verify front-position fitment, emissions certification requirements, and OE interchange before installation. The included gasket and hardware help reduce the need to reuse corroded factory parts.

Quality Assurance

MagnaFlow uses 3D scanning during development to match OE dimensions and function. This converter is designed to meet or exceed California Air Resources Board requirements and has been tested for CARB guideline compliance for legal use in California and other CARB-restricted states on the listed vehicles.
