What makes this a direct-fit catalytic converter?

A direct-fit converter is designed to bolt directly in place of your original equipment, meaning no cutting or welding is typically required for installation, assuming you have the proper tools. It replicates the OE design and mounting points.

What materials is this catalytic converter made from?

The tubing is made from high-strength 16 gauge 409 stainless steel for corrosion resistance, and the welds are durable 308 stainless steel. The body design mimics the original equipment's spun construction.

Is this catalytic converter legal in all states?

This catalytic converter is EPA-compliant and meets Federal emissions requirements. However, it is not CARB approved and cannot be shipped to California.

Product Details

Magnaflow is well-known for making exhaust components that flow well and last a long time. This direct-fit catalytic converter is built specifically for your 2000-2003 BMW M5 with the 5.0L engine, and it's designed to keep your check engine light off by meeting Federal/EPA emissions requirements. It's a passenger side unit that replaces your original part, number 18 30 1 406 813.

This converter uses free-flowing, mandrel-bent tubing, which means the inside diameter stays consistent throughout, helping maintain factory performance and fuel efficiency. The body is made from a strong 409 stainless steel that resists corrosion, and the welds are solid 308 stainless steel. Magnaflow uses 3D scanning to make sure the fit and function are just like the original equipment. The spun body design and a single laser fusion weld help prevent leaks, and its compact size helps with thermal efficiency.

Installation is made simpler because it's a direct-fit unit, meaning no cutting or welding is needed if you have the right tools. Essential gaskets and hardware are included in the box to help you get the job done. Just remember, this converter is EPA-compliant but not CARB approved, so it cannot be shipped to California.
