What do I use to seal joints on pipes

[SpencerA]

Putting my pipe back on and need to know what if anything do you guys use to seal the exhaust joints? Also on the exhaust gaskets do I need to put anything on them or just install the gasket with no silicone? I was reading on the slp website to make sure to make sure the pipes are sealed to avoid hp loss.

I use the Copper color (high temp) gasket sealer, cant remember the exact brand. Any automotive store will have it. I seal all joints between between exhaust components and will give the exhaust manifold gaskets a thin coat. Makes for a nice tight exhaust system with no leaks.

I ended up using the ultra black silicone. Put everything back together and still notice some smoke coming from the manifold. I tried cheating and using the old gaskets, I thought if I put a little silicone on them it would work.

I used red color high temp gasket maker, bought at auto parts store and have had no leaks.

So I recieved top end gasket kit today and had a few questions. First of the exhaust gaskets (4) have two sides, which one goes where or does it matter. What I mean is one side of the gasket is different then the other. Also it came with some O rings that are the same size of exhaust ports, not sure if those are for the exhaust gaskets or something else. Sorry I just don't have any reference of manuals or online diagrams for this old of a motor.
