Magnaflow 03-06 Cayenne V8 4.5 OEM Underbody Direct Fit Converter

If you're working on a 2003-2006 Porsche Cayenne S with the 4.5L V8, this direct-fit catalytic converter from Magnaflow is built to keep your emissions system in check. It's designed to meet Federal EPA requirements, ensuring your check engine light stays off and your vehicle passes emissions tests. This converter is a well-built replacement that replicates the original equipment's fit and function.

What sets this converter apart is its construction. It uses strong 16-gauge 409 stainless steel tubing, which is highly resistant to corrosion and built for a long service life. The tubing is mandrel-bent to maintain the original design and geometry, helping to keep factory performance and fuel efficiency. Magnaflow also uses a single laser fusion weld, which greatly reduces the chance of leaks, and the compact, low-mass design helps with thermal efficiency. You won't need to cut or weld anything to install this part; it's designed as a direct bolt-on replacement, and it even comes with the necessary gaskets and hardware to simplify the job.
