Then how do you know it's the manifold?

What you hear is a tick when the engine is cold, stronger as you open the
throttle, and quieting down within a minute or two?

My favorite method for finding exhaust leaks uses a shop vac. Starting with
a cold engine, duct tape the hose to the exhaust pipe and connect the other
end to the exhaust side of the vac. (It is better if you were able to run
the vac to blow any excess grit out before connecting it to the car.) Turn
on the vac and feel around for the air blowing out. It's a surprisingly
strong stream of air even for a small leak.

Also keep in mind that an exhaust leak allows air to enter the exhaust and
the 02 sensor will read the extra oxygen and try to lean out the fuel mix
to compensate , resulting in possible driveability issues.

I had the car in for an oil change and the guy recommended that he add
this compound to the engine to clean it out. He propped the hood open
and hooked up this bottle of goop. When I fired up the engine some
smoke came out from under the hood and the guy doing the work made the
diagnosis. This was one of those rapid oil change places and I realize
that the workers there have limited knowledge of the vehicles that they
work on, but this guy was in charge of the shop and I have some
confidence in his knowledge.

I've also noticed it is noisy when first started and then settles down
once it's warmed up.

Are they sure they didn't just spill some oil on the exhaust or something?

Sounds like pretty flimsy evidence on which to spend money replacing an
exhaust manifold. If the crack is big enough to emit smoke, it will be big
enough to emit noise.

That sounds like piston slap, not a manifold leak.

If I were you, I'd get a second opinion on that "cracked manifold" thing.
