Your Choice Between a Standard and a Performance Muffler
A muffler is hardly the topic of great conversation, unless of course a person is a distant relative of Milton Reeves, inventor of the Muffler. Regardless of the lack of spirited muffler related conversation, it doesn't mean that it isn't important. In fact, mufflers are of great benefit to a car.
With vehicle Exhaust Systems, the muffler is charged with two tasks. Number one is to reduce noise created by engine exhaust, and number two is to eliminate exhaust back pressure, which can hurt engine performance and fuel economy. However, there are two types of muffles to choose from. The first is a standard muffler and the second is a performance muffler.
Not only do we want fast cars to go fast, but we want them to sound fast too! To this end, tubular designed mufflers like the cherry bomb or glasspacks have gotten quite popular. Their streamlined design allows for excellent flow of exhaust from the motor to the tail pipe. To make the car sound fast, by design, these mufflers do little to reduce engine noise. This is not the type of muffler for the teenager who is trying to sneak out of their parent's house after curfew.
A standard muffler consists of an inlet and an outlet valve, as well as a resonant chamber. The valves work to reduce exhaust pressure from flowing back to the motor. The resonant chamber can reduce engine noise to almost inaudible levels, especially on new mufflers . It's not as flashy as a performance muffler, but they are quiet, efficient and they get the job done. Besides, what soccer Mom wants their minivan to sound like a top fuel dragster?
