I can't tell if thats sarcasm about using the cork gaskets in the exhaust, but obviously that will not work. If you need exhaust gaskets there are a few options.
Pineapple racing has a good selection. They have graphite type aftermarket gaskets as well as OEM gaskets.

Also Remflex makes a gasket for us as well.
