Are you trying to remove the exhaust manifold,the muffler,or just the line running from the manifold connection to the muffler?
Moisture in the exhaust, or a cold running engine.
Could be that the muffler is clogged, it is running extremely lean, or there is unspent fuel burning in the exhaust pipe. This is not completely uncommon and may not be a sign for alarm.

Yes. If you didnt have an exhaust running the fumes away from the cabin of the car, gasses will eventually seep into the cabin and can/will suffocate you to death.
