Installing New Exhaust Manifold - Wrap It?

Did a few searches on this both here and on google but couldn't find much info......I'm replacing a cracked exhaust manifold, any real advantages to wrapping the new one before I install it?

Less heat. That translates into less cracked plastic and rubber parts

Ceramic coat it before you wrap it. You can buy at-home DIY kits.

Wrap keeps heat in the manifold.

I would avoid it.

If at first you don't succeed, use more speed.

Many racers have a one-word nickname for manifold wrap... a "WICK".

Spill oil or gas on it... you can have a fire you won't believe, and can't put out easily.

I have always heard to traps moisture too. May not be a good idea..... well keeping heat away from intake is an excellent idea though.

I too have heard this from old racer's.

I don't know what kind of header/manifold you bought, but keep in mind most manufacturers will not warranty them if they have been wrapped.
