Magnaflow 10-11 Cayenne V8 4.8 OEM Underbody Direct Fit Converter

If you're working on your 2010 or 2011 Porsche Cayenne with the 4.8L V8 engine, this Magnaflow OEM Grade Federal/EPA Compliant Direct-Fit Catalytic Converter is what you need to keep your emissions system in check. Designed to replace the original part, it helps ensure your check engine light stays off and your vehicle runs cleanly, meeting federal emissions requirements for OBDII Federally registered vehicles.

Magnaflow builds this converter using high-strength 16-gauge 409 stainless steel tubing, which offers excellent resistance to corrosion and a long service life. The tubing is mandrel-bent to maintain the original design and geometry, ensuring it flows like the factory part and keeps your performance and fuel efficiency consistent. They use 308 stainless steel for the MIG welds, and their research and development process involves 3D scanning to replicate the OE design precisely. This attention to detail, including a single laser fusion weld, greatly reduces the chance of leaks. The compact, low-mass design also contributes to better thermal efficiency.

This converter is designed as a direct fit, meaning no cutting or welding is required for installation, simplifying the process when you have the proper tools. It includes a flange gasket to help ensure a proper seal. This part is EPA-compliant but is not CARB approved, so it cannot be shipped to California.
