Automobiles especially cars can be upgraded with few modifications done to 
the engine. One of the modification involved in up gradation of the vehicles 
involved adding up of dual exhaust system. Increased combustion of the fuel 
enhances the engine to have better fuel efficiency, more power and higher 
speeds along with reduced pollution and longevity of the cars.
Components of dual exhaust system:
 An exhaust system consists of a set of pipes that carry the exhaust gases 
away from the engine and release it to the outside environment.
 Dual exhaust consists of 2 pipes connected to cylinder heads and the 
exhaust system unit which includes
 Catalytic converter
 Turbocharge
 Muffler
 Tail pipe
 In dual exhaust systems they have the multiple pipe configurations with two 
pipes either placed on two side of the vehicle or both pipes at one end.
Working of exhaust system:
 Engines of any automobile derives power by combustion of gases which 
take place inside the engine and the release of harmful gases are resulted.
 Since the exhaust gases contain harmful or toxic components they are not 
directly released to the atmosphere and are treated before getting out.
 The exhausted gases after their release reach the piping system of the 
exhaust system which usually include many pipes connected to various 
cylinders for collecting the exhaust gases.
 From the pipes the gases enter the convertor where the elimination of the 
toxic materials occur which are present in the exhaust gases.
 Later the exhaust is sent to the muffler where its function is to reduce the 
noise produced by the running engine.
 Finally the exhaust gases leave the system through the tail pipe.
A dual exhaust system helps in improved engine efficiency and performance 
of the vehicle by filtering more exhaust gases away from the engine than an 
exhaust system. An average car has a horse power about 222 but by 
upgrading through a dual exhaust system the horse power is increased by 167 
percent.
The increase of the horse power depends on various factors like:
 Type of the engine
 Equipment attached to the exhaust system
 Diameter of the exhaust piping
Benefits of a dual exhaust system:
Increases horse power and efficiency: Due to increased engine efficiency 
and raised horse power the vehicle lag time in getting high speeds are 
reduced.
Dual exhaust quickly sends out the burnt gases away from the engine and 
more oxygen is brought in fro making the engine to reach peak performance.
Increased sound options: Along with increased efficiency and horse power 
dual exhaust systems lower down the booming sound produced due to engine.
Increased fuel economy: Dual exhaust does not need to work hard to push 
the gases out and bring in fresh air which leads to increased fuel economy by 
making it to make better use of power and produce more energy.
Saves the engine: installing a dual exhaust system also keeps the engine cool 
and increases the longevity of the engine. Due to the continuous flow of fresh 
air in the temperature is kept down by pulling away the hot gases at a faster 
rate
Dual exhaust system enhances the performance of the vehicle in various 
ways. Vehicle owners will gin increase in engine efficiency and horse power. 
Compared to the exhaust system dual exhaust provides with raised 
performance, increased fuel economy, engine longevity and reduced 
pollution.
