| backs and push you all over town. That's because the | | | | your vehicle would sound like a string of M80 |
| majority of your horsepower is generated right there in | | | | firecrackers exploding in a metal trashcan. On the |
| your cylinders through a fairly straightforward process, | | | | other hand, a stock muffler suppresses the naturally |
| called combustion.First, the cylinder sucks a mixture of | | | | aggressive rumble of a strong engine to a spineless |
| oxygen and fuel (gasoline or diesel) into its chamber, | | | | wimper. Take control of the tone of your vehicle with |
| where it is then ignited by a spark plug or glow stick. | | | | a performance exhaust system for the perfect |
| These three ingredients create a controlled explosion, | | | | balance of sound and suppression.Fuel |

| waste gases. That energy transforms into | | | | churning out barrels of Texas Tea in your backyard, |

| horsepower, torque and fun behind the wheel.The | | | | vacuum left behind to keep the cycle running smoothly, |
| problem with stock exhaust systems is that they are | | | | your cylinders empty themselves of more and more |
| not optimized for the best possible flow. Auto | | | | waste gases. And when there are fewer impurities in |
| manufacturers spend much more time thinking about | | | | the cylinder, your mixture of gas and oxygen burns |
