no not really but in the winter months it could be. it can allow cold air into the exhaust ports and cause exhaust valve problems. worst case, it could let flames and heat get into the engine compartment and do some damage. shouldnt be very expensive to fix

For the short term, It should be fine to drive around for a while.
The Exhaust manifold donut I assuming you're talking about connects the back end of the exhaust manifold to the exhaust pipe itself.
Basically the donut seals the exhaust manifold to the exhaust pipe. A poor seal here will allow additional air to be sucked into the exhaust. If you have an O2 sensor after the location of the donut, it will tell the engine that there is too much O2 and cause the computer to inject more fuel. Which will basically cause you to waste fuel, and in the long run possibly burn out the catalytic converter faster.
Short term, other than wasting a little more fuel, should be alright to drive.

Are you sure that it's missing? I'm not being flippant, but alot of the newer vehicles didn't have a 'donut' in them.
If it didn't have one, then it may only have an exhaust-leak, & it may be as simple to fix as tightening the bolts, or it may have a broken stud,,,
IMO you should get it fixed ASAP, as it will create unsafe levels of exhaust-gases in the passenger compartment, & I know that you don't want that in your son's car!

its not the worst thing to let go , however 2.2s have very very very temperamental heads and are prone to cracks between the valves .
if its left un fixed it will allow the head to heat up and cool of faster and we all kow what happens when metal heats and cools fast! CRACK ! id get a new one & put in there. its pretty easy right there in front you can get to it from the top.

It won't cotribute to any major problems, but if the manifold isn't seated properly, it could lead to gasket deterioration

Yes it is bad for him carbon monoxide can enter the passenger compartment and kill him, the fix is easy for him and/or his friends to do and the parts are cheap.

yes it is creating an exhaust leak in the system. which over time can cause valves and guides to burn out due to heat.
