It's attached to the engine, which is grounded, so yes it is.

It is indirectly. The exhaust system is suspended by rubber mounts, which also insulate it electrically. There's a gasket between the exhaust manifold and the engine...BUT the manifold is bolted to the engine block so that will conduct electricity. The engine block is grounded to the frame so through the transitive property, yes the exhaust system is grounded to the frame.
I had to think about that one.

well the vehicle is grounded by being conected to the vehicle itself the motor is grounded and so is the manifold so since the metal bolts touch both the manifold and the motor they two are grounded so if you are testing like the oxygen sensor and you clamp to a bolt on the exhaust and the other end to the sensors power you should see battery voltage assuming you plugged in to the correct pin

No, The exhaust is bolted to the engine(obviously) but from the manifold to the tail pipe it is held on by rubber rings. This prevents the exhaust from damage when the car hits bumps etc..

No, why would it need to be?
