Porsche metal exhaust gaskets - use sealant or not?

[LotusAlfaV6bloke]

A very quick question - when fitting Porsche's metal exhaust gaskets (manifold to head, and cat to manifold) do I use additional products/sealants or fit them dry to very clean mating surfaces?



I have another really long thread on my exhaust system, but this is such a quick question I thought I would ask it on its own. It is a 996 3.6 Carrera.

Thanks,
Chris
