This used OEM Porsche exhaust pipe/muffler, part number 98711312403, is a left-side unit removed from a donor vehicle. Also known as a left muffler or exhaust pipe, this genuine Porsche component replaces parts 98711312402, 98711312401, and 98711312201. It bolts up to the exhaust system on 2.7L or 3.4L flat-six engines (H6) in Porsche Boxster and Cayman models. When the internal baffles break or rust develops, common symptoms include excessive exhaust drone, rattling from inside the muffler, or visible leaks at the welds.
