This used OEM Porsche exhaust pipe / muffler, part number 98711311731, is the left-side unit removed from a donor vehicle. It serves as a combination muffler and pipe section for the exhaust system, reducing engine noise and directing flow out of the car. When the muffler develops internal corrosion or the pipe cracks, you may notice a drone, rattling, or a drop in power. This example was fitted to 2.9L and 3.4L H6 engines in the Boxster and Cayman.
