| skipped out on Auto Shop back in high school, | | | | that stifle your vehicle's rich resonance, |
| I am here to give you a quick lesson on the | | | | rather than enhance it.When it comes to the |
| mysterious inner-workings of your engine's | | | | sound of your vehicle, the muffler has the |
| cylinders. Without cylinders, your vehicle | | | | most impact. Of course, you can tell by its |
| could not drive around, unless you could | | | | name that a muffler's job is to dampen the |
| convince your friends to lend you their backs | | | | sounds pouring out of your tailpipes. Without |
| and push you all over town. That's because | | | | a muffler, your vehicle would sound like a |
| the majority of your horsepower is generated | | | | string of M80 firecrackers exploding in a |
| right there in your cylinders through a | | | | metal trashcan. On the other hand, a stock |
| fairly straightforward process, called | | | | muffler suppresses the naturally aggressive |
| combustion.First, the cylinder sucks a | | | | rumble of a strong engine to a spineless |
| mixture of oxygen and fuel (gasoline or | | | | wimper. Take control of the tone of your |
| diesel) into its chamber, where it is then | | | | vehicle with a performance exhaust system for |
| ignited by a spark plug or glow stick. These | | | | the perfect balance of sound and |
| three ingredients create a controlled | | | | suppression.Fuel EconomyUnless you've got |
| explosion, or combustion, which generates | | | | your own oil derrick churning out barrels of |
| both energy and waste gases. That energy | | | | Texas Tea in your backyard, chances are you |
| transforms into wheel-turning torque to | | | | too are feeling the pinch at the pump due to |
| propel you down the road, but the exhaust is | | | | the rising costs of gasoline. And while it |
| a cloud of useless particles that would clog | | | | might sound too good to be true that you can |
| up your engine if left to linger in the | | | | get better fuel economy along with serious |
| piston chamber.That's where the exhaust | | | | performance boosts, we're not pulling your |
| system comes into action. The spent gases are | | | | leg.That's because the same overall |
| exhaled, traveling out of the engine through | | | | improvements that lead to greater performance |
| your exhaust manifold, and they eventually | | | | are improving your engine's overall |
| exit out the back of your vehicle. The faster | | | | efficiency. You see, when the exhaust is |
| the exhaust gets out of the way, the easier | | | | flowing unrestricted down wider pipes with |
| it is for your engine to breathe, which means | | | | the right amount of vacuum left behind to |
| more horsepower, torque and fun behind the | | | | keep the cycle running smoothly, your |
| wheel.The problem with stock exhaust systems | | | | cylinders empty themselves of more and more |
| is that they are not optimized for the best | | | | waste gases. And when there are fewer |
| possible flow. Auto manufacturers spend much | | | | impurities in the cylinder, your mixture of |
| more time thinking about the shape and | | | | gas and oxygen burns purer, giving you |
| placement of your air vents than they do | | | | greater horsepower without having to have a |

| work harder during combustion, which robs you | | | | around a 1 or 2% overall increase in fuel |
