Everyone is looking for ways to get more for less. Most methods used usually have a catch but the method discussed in this article is clear and simple and does not have any hidden costs. Whichever car you drive, there are various suggested ways of increasing your power usually costing more than you would be willing to give. This article presents an argument for glass pack mufflers as an old, simple and inexpensive way to significantly increase your engine power at a lower cost.

What is a glass pack muffler?

This section gives the basics for those users who are not into all the car jargon. There are many types of exhaust mufflers depending on the model of your car, weight, cost and so on. Glass pack mufflers are more of an accessory and can be fitted into any kind of vehicle. They are simply a type of muffler where the exhaust gases pass straight through the center of the muffler with fiberglass surrounding the exhaust channel to absorb some of the high frequency sound.

The first make was released in 1968 under the trademark cherry bomb (you may find that most people know them by this name) and it features a straight through design. Improvements have been made since then but it is basically made of welded, aluminized steel designed to be reversible for ease of installation.

How it works

As we all know, mufflers are designed to reduce the noise produced as the high pressure exhaust gases pass through constricted space. Without them our roads would be unbearably noise polluted zones. Although they do this great service, it is always at the expense of the engine power. They are constricted and therefore impede the flow of gases and increase back pressure. This in turn affects the power and torque of your engine. This means that you have to choose between noise and back pressure.

The makers of the glass pack mufflers found a way to get both through a design that allows direct flow of gases through the exhaust pipe greatly reducing the back pressure hence improving performance by letting out gases even faster. The fiberglass barrier, though not as effective as conventional mufflers, absorbs some of the high pitched sound.

The trade-off

Finally, there is always an advantage and a disadvantage in the use if any product. As mentioned, the glass pack mufflers will produce a louder sound as compared to others. To counter this, some manufacturers such as MagnaFlow put extra acoustic packing material to muffle the noise even more. Since you are more interested in increasing the power, then this is more of what you want than what you do not. Try them out!
