With features including free-flowing mandrel-bent tubing and highly corrosion resistant stainless steel construction easily install this spun body converter yourself using the proper tools no cutting or welding required. MagnaFlow's state-of-the-art metrology department uses the latest 3D scanning systems during research and development so you can be confident that your new part will fit and function like the original equipment. By replicating the OE spun body design the single laser fusion weld greatly reduces the possibility of a leak and our compact low-mass design also allows for greater thermal efficiency. This direct-fit catalytic converter is designed specifically for the 2010-2011 Porsche Cayenne. The included gaskets & hardware reduce the possibility of a leaking seal while avoiding the need to reuse corroded factory parts for installation. This replacement part is designed to meet or exceed California Air Resource Board requirements and has undergone additional testing to comply with CARB guidelines to allow for legal use in California and CARB restricted states for the listed vehicles.
