Same, I have never seen it either. And it doesn't look some homebrew job either.

It is only one side and protects the shift linkage.

The picture is of my 4/98 base which has an interesting assortment of the 97 and 98 MYs. However the OP says his is what an 01 ? so more likely related to base cars? And pay no attention to the exhaust bracket that was a mod I did with an 03 S muffler.

My '02 base had that shield. I forgot to put it back on after some work I was doing, and the car has survived just fine ever since then.

The rubber/plastic baffling on the bottom aluminum pan is different on the base 2000-04 too. I'd recommend leaving it if you plan on tracking your car. I believe it has to do with cooling the transmission/Cv and heat is what kills transmissions.

That heat shield is there to prevent radiant heating of the shift linkage by the muffler. Although at speed the turbulent air under the car eliminates convective heating, it does nothing about radiant heating.
The Porsche engineers put it there for a good reason; removing it saves, what, a few ounces of weight, and shortens the service life of the rubber parts in the shift linkage.Poor tradeoff.

My 03 s has a different sort of heart shield. It's more like 2- sided, maybe 4"x6" each side, louvered, and screws to the "top" (bottom of the trunk). It seems at some point they decided that was enough?

The 6 speeds got a smaller heat shield that was closer to the shifter links that's only purpose was to protect from the exhaust. Tiptronics never got any metal heat shield in the 986 even though the shifter cable is closer to the muffler
