Mufflers & Resonators

Aluminum & Stainless Mufflers, Combination Mufflers/Tail Pipes

While your car is never complete without the exhaust system, the latter one is hard to imagine without a muffler. The part (aka backbox) serves to both lessen emissions and reduce sound pressure produced by the engine. It is the exhaust system's silencer so to speak. Without the muffler, the engine would create sounds similar to those a rocket produces. To cancel out that noise, the unit uses a pretty neat technology.

The muffler consists of metal plates and tubes with multiple holes in them. Between the tubes, there are chambers that cancel out the unwanted frequencies and suppress the annoying noise. Once the sound waves and exhaust gases move into the muffler through the center tube, they bounce off the back wall of the unit and then come back out into the main body. That creates waves that have the opposite amplitude, which makes them cancel each other out.

The chamber where the process of wave collision occurs is called the resonator. Its size is precisely calculated so that the process runs smoothly. The principle that the device works on is pretty simple. When the high-pressure sound wave that is coming out from the first chamber meets the reflected low-pressure wave, they cancel each other out because the two waves add up to zero. That's the way the muffler reduces that tremendous amount of noise produced by the engine.

Another important characteristic of the muffler is that its body is constructed in three layers: two thin metal layers with a thicker insulated layer between them. Such a structure allows the unit to absorb some of the pressure pulses. The muffler itself is manufactured from sturdy materials such as stainless steel and aluminum-coated steel. That ensures the part to function for a long period of time. And the better your muffler operates, the greater performance your vehicle offers.

To avoid catastrophic consequences, every driver should have their vehicle checked from time to time to make sure the muffler and the rest of the exhaust system components are in good shape. Keep your ears and eyes open for anything unusual about your emission system. Compared to other components of the exhaust, damage to the muffler is much easier to detect because of the increased noise level. So, if your vehicle is noisier than it used to be, or you notice a dip in your vehicle's performance, it means the muffler's days are numbered.

Guides & Articles
Regardless of whether you're shopping for a simple replacement muffler that delivers original equipment (OE) sound and performance or an upgraded muffler which provides a deeper growl with increased power through freer exhaust flow, you'll see choices between "direct fit" mufflers and "universal" mufflers. In this article, we'll help you understand the differences between these two styles so you can make a more informed purchase.
