Default exhaust sealer

hi
my assembly manual indicates a type 82a grease based sealer at the joint between the front and rear exhaust pipes, where they connect just forward of the trans cross member. it seems as though a grease sealer would burn out of this joint.
does anybody know what this stuff is?
thanks
jeff

I'm not familliar with the grease you mentioned but it might be Moly they're referring to. It very high temp stuff, also called antiseize compound used on threads. It will not burn off when applied to exhaust pipe joints. Molybdenum Disulphide.

The AIM lists it as SEALER-GREASE BASE Part # 9985020 and that looks like that is the only place it is used.
