Aluminized Mufflers & Pipes

Aluminized Muffler and Pipes

 

Purpose of the Muffler

 

The muffler is one of the most neglected parts on the car, but it’s also one of the more important. Its purpose is to reduce the sound of the engine firing, and it does this through means of a small noise reduction chamber that helps to cancel out sound. It can also be used to help direct exhaust away from the vehicle, and it often comes with some type of packing (like fiberglass) to help with the noise reduction.

 

How They Work

 

The construction of a muffler is surprisingly simple. A standard muffler will have four primary parts. You’ll find an inlet and outlet valve, the housing that holds them, and a resonant chamber. As gas moves through the engine and flows into and throughout the housing chamber, that noise is cancelled out by the resonant chamber. While the majority of noise reduction happens this way, the packing inside the muffler (again, typically a material like fiberglass) can also help to reduce the noise produced.

 

What are Aluminized Steel Exhaust System Made of?

 

Aluminized steel mufflers are the better choice, as they tend to last longer than others. An Aluminized muffler is a steel muffler with a thin coating of aluminum to help ward off the oxidation process, and thereby extend the life of your muffler. These mufflers are cheaper than their stainless steel counterparts, and are more readily available.

 

Benefits of Aluminized Steel (lighter, good for dry climates, thick tubing, less expensive)

 

First off, these are the cheaper mufflers. They are also extremely strong, and have thicker tubing to handle more exhaust. Drivers of performance cars tend to like aluminum for its weight (it’s very light.) Also, if you happen to live in a dry climate, aluminized steel tends to hold off oxidation longer than stainless steel. Because of these features, and also because of the price, these are great mufflers if you don’t care too much about appearance, or if you are looking for a more cost-effective option.

 

What Can Go Wrong?  

 

While aluminized steel is a viable option, there are some downsides to going this route. First off, they can appear dull next to the polished steel look of a stainless steel muffler. If you’re going for aesthetics, then you may want to consider another option.

 

Second, all it can take is one scratch to ruin an aluminized steel muffler. If there is a nick in the metal coating, it’s very easy for moisture to get in and corrode the muffler, leading to you having to do a costly replacement far sooner than you probably planned.

 

Finally, they’re just not as durable as their stainless steel counterparts. While lighter, you’re trading durability for weight, and depending on your needs as a driver, this may not be the way you want to go.

 

Your muffler is an important piece of your automobile, and one that many people simply don’t think about. The choice of muffler you purchase is completely up to you. Just remember, if properly cared for and maintained, it can last you for years.
