One problem related to manifold/header/muffler/tail pipe has been reported for the 2001 Porsche 911 Turbo. The most recently reported issues are listed below.
Water manifold has press-fit epoyy connections that have been known to come loose. Mine did and I lost all of my coolant. It blew across the whole engine bay and over back tires. Very dangerous as a car spun out of control behind me as well. Took engine apart and welded two of the fittings but several others remain oem. Expensive fix thus far, and not yet done. Very poor design and dangerous!!.
