No.. If anything it makes it slower if you do not have the right muffler or exhaust system on it.

No. not earthly vehicles. Some spacecraft have ion engines (at least they have been proposed).
To tell the fuel injection what to do.
As a rule exhaust is emitted on the opposite side of the fuel filler tube on single exhaust vehicles for safety reasons.
The primary exhaust gasses of the internal combusion vehicle are carbon dioxide, carbon monoxide, and water vapor.
Oxygen sensors are located in the exhaust manifolds & in the exhaust pipes on most vehicles
O2 sensors are located on the exhaust system in todays vehicles, they monitor the oxygen levels in the engines exhaust gases. They send that information to the vehicles computer which inturn regulates the engine's fuel system for a clean burn.
Sulfur
in some cases if the exhaust is rubbing on the gas tank most new vehicles have poly plastic tanks and most of them have heat shields covering the exhast older vehicles have steel gas tanks
