Yes, without a proper exhaust system in the car carbon monoxide can enter the passenger compartment and kill you.
BAD
put car on lift,remove exhaust system,put car in gear and watch driveshaft wobble!
No. have exhaust checked/repaired
Well if you have a hole in your exhaust like rite under your car, it is able for the exhaust fumes to get into your car and kill you ;P
Yes. A car can run without an exhaust manifold. It will burn out the exhaust valves in the cylinders a lot faster than normal, but it can be done.
No. A catalytic converter wont. If its a rear wheel drive, check your drive shaft. Front Wheel drive, CV Joints. Other than that worn steering. Exhaust wont cause this issue.
A headache or worse.
That is oil. VERY BAD!! You need to take your car to your garage right away. You should know this, I'm not even old enough to drive and I know this.
What can cause black sooty exhaust is bad valve guides. When the guides are bad oil leaks into the cylinder when the car isn't running. When the car starts it produces black exhaust.
No! It is illegal to drive a car without a licence.
You can not, and should not drive a car that has a bad water pump. The water pump pumps coolant through the engine. You engine will overheat and die without a functioning water pump.
No it won't hurt the engine BUT you could get carbon monoxide in the car. Don't sit in a parked car with the engine running if your exhaust is bad - it could kill you.
