Default Exhaust gaskets with high temp silicone?

When changing exhaust gaskets on a 3.2 does anyone use high temp silicone goop or something also to help seal or hold them in place?

Put them on dry, just like the factory did. If they fall down put a little dot of grease near each stud hole, just to hold them while you attach the exhaust.

Thanks Pete. Will do.

Any torque values or just nice and tight?

If you intend to remove these in one piece sometime in the future, don't forget the antiseize (on the threads).

Olav: I'm not sure where my earlier comments went, but I'll post again for you. A lot of people use silver anti-seize, I don't and never have. I prefer copper paste, also an "anti-seize", that's made by Lubro Moly (LM 508) and sold, I think, by Performance Products. Put a dab of the stuff on the male threads and tighten normally. Regarding torque, most 8mm hardware on 911s is torqued to about 18 lb/ft, so nice and snug is enough. Don't get muscular, those studs can break!

Copper nuts can also be used, which pretty much guarantees they will come off years later without hurting the stud....

Great! Thanks for the feedback especially on how tight to bolt em on. I'm always afraid that if it's not super tight I'll get leaks.

The copper nuts are a factory part, use them with a little copper anit seize and you will be set.

Cheers
