Fabspeed Porsche 957 Cayenne V6 Sport Performance Package (2008-2010)

Why We Choose HJS Catalytic Converters:  HJS German imported catalytic converters are made from some of the highest grade materials you can find in a catalytic converter. This yields high performance gains and longevity so it wont deteriorate over time like lower grade catalytic converters. These catalytic converters flow up to 93-95% of a straight pipe in most applications. The benefit is that you get the "straight pipe sound" while still being able to provide enough emissions scrubbing to prevent a check engine light.     Complete high-performance exhaust & intake solution for the 957 Cayenne V6; includes Maxflo Mufflers with Deluxe Quad Style Tips, Secondary Catbypass Pipes, Fabspeed ECU Tuning Upgrade, and a BMC F1 Replacement Air Filter                                                                  INCLUDES: 957 V6 Maxflo Performance Mufflers incl.
