what does an exhaust system consists of?

keep in mind that they have a lot of effect on your car.  A manifold is often replaced with a header. The issue with headers is 1)  Even Tube and 2) Long tube vs. Short Tube.  The next issue is catalytic converters vs. none vs. high flows.  Another issue is pipe length and diameter.  \nChanging these will have various changes on your car.  It is often misunderstood.  Most people think free flowing = more power = faster.  This is right and wrong at the same time.  These items will also control were your engine makes it's horsepower and torque within its rpm range.  You need to find out how you plan on driving, what transmission (torque (stall) converter setting) vs. standard trasmission, if you plan on racing and what type (stop light to stop light vs. quarter mile vs. rally)  these are all different and require different set ups.

Essentially the metal parts of your car form an electrical circuit.  Electricity flows from the negative terminal of your battery, through the frame of your car, and back into the positive terminal of the battery.  In theory cars are not well designed from an electrical standpoint so the ground wires make the flow of electrons through the body of the car easier, which should improve ignition and audio system performance.

In the third stroke.  The cycle goes: intake, compression, POWER, exhaust.

Simple. An engine makes its own power from fuel (usually internal combustion) and a motor takes its power from an external source (usually electricity). Regardless of what others here are saying.

These answers are all correct yet incomplete.\n\nFor complete combustion of a hydrocarbon (the major components of gasoline are hydrocarbons), the products are water and carbon dioxide.\n\nHowever, combustion in the everyday use of gasoline is not necessarily complete, and the products due to incomplete combustion of a hydrocarbon are water and carbon monoxide.\n\nAlso, in theory, the combustion occurs when oxygen and hydrocarbon are chemcally reacted with each other.  However, in practice, the oxygen supply comes from air, which is predominantly nitrogen, and the heat of combustion will contribute to the combustion of the nitrogen.  The products of combustion of nitrogen are NO2 and NO3, commonly known as NOx.\n\nThe main fact left out in the previous answers, are that gasoline is not solely composed of hydrocarbons.  In addition to the fuel additives, which are predominantly formed from carbon, hydrogen, and oxygen, there are also sulfur-containing organic compounds that are considered impurities (ie, could not be removed during the refining process).  The products of the combustion of these sulfur-containing compounds are carbon dioxide, carbon monoxide, water, and SO2 and SO3, commonly called SOx.\n\nCombustion of gasoline will also have particulate matter as a byproduct. Is is similar to smoke you see when burning any fuel.  Incomplete or inefficient combustion can lead to small amounts of carbon not being oxidized, leaving carbon dust, or coke, as a product.  This dust can also be a carrier for other pollutants or by-products and depending upon particle size, can be very harmful to human respiratory health.\n\nFinally, since some of the fuel may not be completely combusted, volatile organic compounds, or VOCs, will be products as well.

Here is the "How Stuff Works" website devoted to cars. It has pictures of many of the mechanical systems of automobiles. Very informative.

You can't go wrong with a high flow exhaust and a high flow air filter, it helps the engine breathe a lot better and should also increase economy.  It might be a bit louder though...

Better flow of the exhaust (which increases performance) vs the stock exhaust.

The gasket may be blown.  Are you getting excess exhaust/fumes?

depends on what muffler u get. many do a great job, look at ones from Flow master, Borla ,Hooker just to name a few. They all have specs on what they sell. After market Headers will inprove the over all flow of exhaust gas as long as u upsize the down pipe and main pipe all the way back to the muffler. Use only stainless steel and stay away from the cheep crap.  also get a NEW o2 senser so the computer can know what is going on. Bosch makes a good one.

Major Components of Ecosystems:\n\nEcosystems are composed of a variety of abiotic and biotic components that function in an interrelated fashion. Some of the more important components are: soil, atmosphere, radiation from the sun, water, and living organisms.

are we talking engine parts like block, cam, head, ect....if so try hear.  the second one goes more in depth

There have been different systems in the past 30yrs. For a general concept check out the link below.\n\nDepending on what you are looking for: EFI electronic fuel injection, TBI throttle body injection, CBI central body injection, CPI central port injection or SCPI sequential central port injection or MFI multi-port fuel injection (which is most popular nowadays) you can get an idea of what it is at this link.\nFor a specific version based on the vehicle you own, try a Hanes service manual.

Hard to say without a picture or to see the process. Gas pressure? Wind? Contaminants in the metal? Wrong gas mixture?\nHere's a couple of links that may help..

This is either a pipe or tube (i.e. muffler pipe for your automtoive is made this way) that has ben bend from flat metal into a tube shape and then welded together to form a solid pipe/tube.\n\nA good explanation can be found at:\nhttp://www.thefabricator.com/ResistanceWelding/ResistanceWelding_Article.cfm?ID=89\n\n\nOther sites that will give more inforamtion:\nhttp://files.aws.org/wj/supplement/01-2004-CHOI-s.pdf\nhttp://www.usstubular.com/facilities/erw.htm\nhttp://www.lbfoster.com/piling/pipepile.html\nhttp://www.weldingengineer.com/1%20Resistance.htm\nhttp://www.ipsco.com/Products/TubularProductManual/TubularProductManualERWIntro.pdf\nhttp://www.phamitech.com/pd_tubemill.htm\n\n\nHope that you find these sites useful.\n\nGood Luck.
