I'm still not convinced; if you look in the Porsche parts list for the U shaped connector pipes (#18 in the diagram) that go from the muffler to the cat pipe, you will find that the S pipe is a different part number than the 1999 base pipe. You would also find that all the parts for the base cat pipe (#5 in the diagram) are smaller in diameter, all the way to the triangular gaskets where the cat pipes bolt to the manifolds.
