Best Sounding Muffler: Important Features

A good muffler should be able to produce the right growl, rumble or roar to back up your car’s performance and look. The sound of a high performing muffler can be anything from a low, throaty growl to an ear-piercing roar.

That is why it is important for the car owners to choose the best muffler for their vehicle. Here are some of the important muffler features that you should consider when buying:

Muffler Materials

sounding muffler materials

Choose a muffler that is made of high-quality materials. Make sure that it can handle high-pressure exhaust gases. It should be something that resists rust and absorbs the impact from road debris.

A good muffler should have a 3-layer body comprising a slightly isolated layer in between, an inner case and an outer covering.

The muffler body is either made of stainless steel or is aluminized. The main advantage of using an aluminized steel muffler is the cost, but it is prone to rust and may only last for four years.

The stainless steel mufflers, on the other hand, are more expensive but can last ​up to ten years. ​They offer superior rust resistance and are very durable ​ compared to aluminized steel. Some may be packed with steel wool or fiberglass to add to the reduction of sound.

Inlet, Diameter and Fit

You need to determine the number of inlets you require for your muffler. You can choose from the single or dual system. If you have a single exhaust, then you need a single inlet on the muffler. In case you have plans of uniting two exhausts, into one muffler then you should buy a dual inlet exhaust.

When it comes to diameter, the inlets and in some instances also the outlets should match your present exhaust diameter.

You should also consider how much room is available for the muffler. Make sure that the outside dimension of your muffler will fit under the vehicle. To ensure proper clamping and for ease of installation, you need to choose the right length. Choose the right shape and casing size so it will fit perfectly within the confines of your car’s undercarriage.

Choose the Right Style

There are three styles of muffler available in the market – the chambered, straight-through and turbo. Each design has its own pros and cons.

sounding muffler types

Chambered muffler

This is perfect for muscle cars and street machines. A chambered muffler can reduce ​exhaust noise and provide a throaty performance sound. It has inner chambers that are constructed at certain lengths to echo sound waves against each other. Some manufacturers use sound-deadening inserts or baffles to reduce the sound even further.

Turbo Muffler

It is a set of perforated tubes, which guide the exhaust gasses into the mufflers in an S-shaped pattern. The design is restrictive ​compared to other types; the S-design lets the gasses travel to the tubing to reduce noise further.

Best for street applications, other turbo-style mufflers have a sound reducing material with tubes for increased muffling.

Straight-through muffler or glass pack

Allow maximum flow and horsepower. This muffler is a straight, shaped pipe wrapped in sound absorbing material like fiberglass packing. Best for racing.

It allows the exhaust gas to flow into the pipe with less restriction but offers less sound reduction as compared to chambered mufflers. The design is more compact than any other muffler styles, making it the popular muffler for custom car builders and street rodders.
