I agree that the 9R6 exhaust looks to be gold foil on the outside but look at how thick it is. There is a good, 1/4 inch to my eyes, of some sort of insulating material like a sponge below the gold foil. It seems to be very porus and with an irregular, cratered surface that is wrinkling the gold foil. You can see the bare header closer to the silencer/diffuser/"muffler" on the side of the car. It is much smoother and a good bit smaller in outside diameter.
