MagnaFlow Conv DF 03 Mazda 6 3.0 Rear Manifold

If your 2003 or 2004 Mazda 6 is showing a check engine light related to emissions, it might be time to replace the manifold catalytic converter. This direct-fit unit from Magnaflow is built to meet California Air Resource Board (CARB) requirements, making it legal for use in California and other restricted states. It's designed to replace the original converter without needing any cutting or welding, simplifying the installation process significantly.

Magnaflow uses highly corrosion-resistant stainless steel for the tubing and a durable 308 stainless steel for the MIG welds, ensuring a long service life. The converter's body replicates the original equipment design, and a single laser fusion weld is used to greatly reduce the chance of leaks. Inside, the free-flowing mandrel-bent tubing helps maintain factory performance and fuel efficiency, while the compact, low-mass design allows for greater thermal efficiency. Magnaflow's research and development team uses advanced 3D scanning to ensure this converter fits and functions just like the original part.

To make installation as straightforward as possible, this catalytic converter comes with the necessary gaskets and hardware. This means you won't have to reuse old, potentially corroded factory parts, and you'll have a better chance of achieving a leak-free seal right away. This part is designed to interchange with OE parts like AJ57-20-55XC and AJB4-20-55XB.
