Installing metal exhaust gasket

[TheyKilledKenny]

Im guessing using sealant/gasket maker would be pointless since it would probably just burn off?

You need to be more specific.
Where on the exhaust?
Yes liquid gasket is point less in all applications, you can use reinforced high heat rubber ones on the exhaust after the cat , but for sure not for the manifold.

I've used hi temp copper silicone with zero issues on more than one application. Manifolds, turbos, etc. it is sensor safe.

I use copper spray/silicone for headers and turbos and the red for the downstream stuff

Oh its for my manifold, I have the copper RTV but Im wondering if it will hold up to the heat.

Does it have a max temp on the container?

Usually thick metal gaskets work just fine on their own, But I would only use high temp silicone if I have taken it apart and used the same gasket too install it again.

I have the Permatex Copper RTV, says its good for 371C (700F) Intermittent

You can get the exhaust gasket sealant from places like performance improvements, designed for use on turbo applications. Great for when you start tuning as exhaust leaks will mess with your afr readings. Wish i bought some when buddy at the store recomended it.
