Choose the Right Muffler for Your Car

Car Muffler

If your car sounds louder than normal, the problem could be from the exhaust system. Among the solutions mechanics recommend is to install a muffler to minimize exhaust noise levels.

Different types of mufflers are available depending on the design of your car's exhaust system. But before installing a muffler, learn how this device works and the type your car will need.

Here is a quick guide to mufflers, including how to select the right one for your car.

Muffler Basics

A muffler is a device you install on the exhaust pipe to minimize noise from the car's internal combustion engine. When internal combustion occurs in the car's engine, the exhaust valve opens to let out hot gas from the combustion chamber into the exhaust system.

The high-pressure gas from the exhaust chamber interacts with the low-pressure gas in the exhaust system and passes through the exhaust pipe at a high speed.

As the gases pass through the tailpipe, the engine works harder to release these gases, which can lead to power reduction. Mufflers help to maintain the engine's performance and power.

Muffler Types

Numerous types and brands of mufflers are available in the market, but these devices generally fall into one of two categories. These include sound restricting or sound absorbing mufflers. Some muffler designs are a combination of restrictive and absorptive technologies.

Sound Restricting Mufflers

Sound restricting mufflers generally feature internal sound chambers and perforated tubes through which gases from the engine pass. These are also known as chambered mufflers.

The restrictive nature of this type of muffler is effective at minimizing loud engine noise down to a bearable but aggressive sound or to a completely silent exhaust sound.

However, this type of muffler can create excessive back pressure. Too much back pressure can minimize your engine's power. A reputable mechanic will help you select a good quality muffler that will not generate exceedingly high back pressure.

Sound Absorbing Mufflers

Sound absorbing mufflers contain an absorptive packing material that captures the sound waves entering the exhaust tailpipe. The muffler essentially converts sound energy into heat energy, which flows out through the tailpipe. These are also known as flow-through mufflers.

Depending on the noise cancellation mechanism, sound absorbing mufflers can help to produce a well-defined but powerful exhaust sound.

On the downside, the absorptive material in this type of muffler can burn out quickly, especially in lowquality mufflers. Your mechanic should be able to recommend a sound absorbing muffler brand with a longer service life.

Whether you need a sound restricting or sound absorbing muffler will depend on the exhaust tone you prefer.

Exhaust Design

Another factor that will determine the appropriate muffler for your vehicle is the exhaust design. The two types of exhaust designs are single and double. A single exhaust will need a muffler with a single inlet while a double exhaust will require a muffler with two inlets.

Mufflers come in different shapes and sizes. The right size muffler will depend on the diameter of the exhaust pipe.

On the other hand, the shape of the muffler will depend on the clearance space underneath your vehicle. The shape, size, and length of the muffler's casing should fit snugly in the undercarriage.

Whether you want to bring the exhaust noise level down to a barely-there murmur or you want to create a more defined but high-performance sound, a high-quality muffler can get the job done. Proper installation is crucial for the performance of both the muffler and the engine, so be sure to have a professional mechanic install your muffler.
