Answer 2

Mufflers are chambers at the end of the exhaust that calms the sound of your exhaust. here's a better explanation from vdubpartdirect.com "The said chambers and baffles are called as resonators that are primarily linked at the first chamber of the VW muffler using an opening. This resonator typically possesses a certain amount of air and has a precise total length that is pre-calculated to produce a wave that can either absorb or cancels out a certain frequency of sound. When a wave hits the hole, part of it continues into the chamber and part of it is reflected to the source as it is cancelled out in the process by colliding on the same wave form. The wave that is moving towards the chamber bounces from the back wall of the muffler and back to the hole as it repeat the process of cancellation. "

The car exhaust means the reject gas emitted from its engine. The exhaust gas contains peroxyacetyle nitrate (PAN) along with a host of other poisonous gases e.g. Carbon dioxide, carbon monoxide, etc. which is quite injurious to living beings including flora and fauna.

Car Exhaust Functions at a Glance:

The main function of a car exhaust system is to provide an easy and durable way of exhausting (venting) hot gases from the combustion chamber. In order to withstand blistering hot temperatures of the exhaust gases, the car exhaust systems are usually made from cast iron. Furthermore, in order to free the engine compartment space, car exhaust systems are made compact in size.

The manifolds of a car exhaust system are tuned. The design of the exhaust part is made in such a way as to facilitate the smoothest, free flow of the used gases. Yet, for optimization of performance, the flow is restricted to some extent. This results in the speeding up of the air flow, which is also known as the “venturi effect”. By making use of this technology, the engine performance is optimized which shows while the driver accelerates or decelerates.

The main function of the mufflers and resonators are to minimize the sound of the engine’s exhaust. In the absence of these accessories, the engine’s exhaust could sound terribly noisy and disturbing. Inside the mufflers and resonators, passageways or baffles are built. The exhaust gases are channelized through these baffles. This results in a significant lowering of the noise due to the engine’s exhaust and produces the desired muffling effect.

So if you are looking for building up the horse power, freeing up the trapped torque and rectify the anemic sounding factory systems of your vehicle, it’s time you go for an up gradation of your car exhaust system. A well-designed car exhaust system having larger pipes, low-restriction mufflers and tuned resonators can give the required boosting to your car!

Answer 4

The exhaust is the product that is left over after the power stroke, it will exit the header and go to the catalytic converter and then to the muffler and out the exhaust pipe at the rear of the car. In some other cars it may also be used to power the turbocharger too. good luck

Answer 5

the fumes left over after the engine has combusted the gas/air mixture. If you get an upgraded exhaust the bigger pipes allow for more airflow especially when combined with an intake and produce a small amount of horsepower. Otherwise it is just waste from the car that is filtered by your catylitic converter and quieted by your muffler

Answer 6

The exhaust pipe on a Brit's car is the same thing as the tail pipe on an American car - just as the trunk of an American car is the boot of a Brit's car

Answer 7

its what your engine produces when it burns up its fluids like gasoline and oil.
