Aftermarket Exhaust

• An aftermarket exhaust is generally larger in diameter than the stock exhaust and features a more free-flowing muffler. The purpose of a performance exhaust (along with a better sound) is to get spent engine gases out of the car as efficiently as possible. This allows the engine to run more efficiently and make more power.
  
  

Aftermarket Chip

• Put simply, an aftermarket computer chip remaps the ignition system with different fuel and air settings for a power gain.
  
  

Aftermarket Intake

• The side of the engine where air comes in is referred to as the intake side of the engine. In stock form, most air intakes are restrictive. By replacing the intake with larger diameter tubing and a free-flow air filter, more air is delivered to the engine for more power and usually better throttle response as well.
  
  

How They Work Together

• These three parts will generally work together to varying degrees. The additional air from the intake is matched with the added fuel, spark and timing from the chip. The exhaust then gets the engine's spent gasses out of the engine more quickly than a stock exhaust. The result is more power and response from the engine.
