A muffler is arguably one of the most cost-effective ways to mod your car. For just under a hundred bucks, a muffler could dramatically change the way your car sounds – from a deep rumble to a throaty roar, the right muffler could complement the sound of your turbo car.

So, if you’ve decided it’s time to let your turbo car roar freely with a performance muffler, then keep reading as we’ve picked out the 5 best mufflers for turbo cars that are sure to sound amazing and even provide a slight performance boost.  

Which Muffler Style is Best for Turbo Cars?

There are three main styles of mufflers: straight-through, chambered, and turbo.

You might think that the turbo style muffler is the best choice – after all, it’s called turbo for a reason, right? Well, not quite. If anything, a turbo-style muffler has the worst balance of sound and power because of its restrictive design, and for that, I would definitely not recommend running a turbo muffler.

The reason why turbo-style mufflers are called turbo is that the first production example of the muffler was designed and used on the 1965 Chevrolet Corvair Corsa Turbo. They are the quietest and most restrictive mufflers on the market.

With that out of the way, the best muffler style for a turbo car should have a balance of both power and sound.

There is a saying that the only muffler a turbo car needs is the turbo itself and it actually holds value. On lower revs, straight piped turbo cars are actually pretty tame and moderately quiet, however, once on boost, a turbo car does make a lot of noise. Thus, if you like your cars loud, consider doing a muffler delete.

A chambered muffler is a combination of straight-through and turbo. If you’re concerned about drone and that the car will be way too loud, a chambered muffler may be the right choice. It’s not as free-flowing as a straight-through muffler but it’s significantly quieter.

On the other hand, if you don’t mind a louder exhaust and a bit more drone, consider a straight-through/glasspack muffler. A straight-through muffler will significantly reduce backpressure, thus increasing horsepower and throttle response.

In the end, it all comes to the design of your car’s engine and the exhaust system. On some cars, a chambered muffler sounds too quiet, while on the others it’s perfect.

The best advice I can give you is to test the sound of your car with no muffler. If the car sounds way too loud with no muffler, get a chambered style muffler. But, if your car sounds almost perfect without a muffler (in most cases it does), get a straight-through to cut down on a couple of dBs.

The Laminar technology used in the Super HP-2 series uses two opposing conical structures to shape the sound of the exhaust gases into a powerful, deep tone.

The compact oval shape of the muffler, allows for easier installation and fitment, while the Flowmasters Cool Shell technology significantly reduces the temperature of the muffler’s jacket.

Because of the lower external temperatures of the Super HP-2, the muffler can be installed in tighter spaces without the fear of melting the floorboards of your car.

How To Buy The Best Muffler For Turbo Cars


The fitment of the muffler should be one of the main aspects to consider before buying, as they come in a variety of shapes and sizes. It’s recommended to check if the muffler of your choice is small enough to fit under the car, without compromising the strength of the whole exhaust system.

The diameter of the inlet and outlet of the muffler should match the diameter found on your exhaust pipe. If the diameter does not match, you’ll have to use an adapter to complete the installation. 


As discussed in the first part of the article, there are three main muffler types: straight-through/glasspack, chambered, and turbo.


A straight-through muffler, also known as a glasspack because of the sound dampening fiberglass material found inside the muffler, is as simple as it sounds. This type of muffler allows for maximum airflow by allowing the exhaust gases to move straight through the muffler with minimal resistance. In order to reduce the sound, glasspack mufflers contain a perforated pipe, with fiberglass wrapped around it. The fiberglass material insulates the outside casing of the muffler and dampens the sound waves.

The straight-through is the least resistive of the three and therefore the loudest. For some cars, it’s the perfect choice as it provides an excellent balance of power and sound.


A chambered muffler is a combination of straight-through and turbo style mufflers and sits between the two when it comes to sound level. These mufflers are quieter than the glasspacks but louder than the turbo-style mufflers.

As the name implies, chambered mufflers use chambers to bounce the sound waves and condition their wavelength. With the use of advanced fluid dynamics and calculations, chambered mufflers cancel certain high and undesirable wavelengths out and highlight the deep and aggressive tones.

Chambered mufflers are the perfect choice for cars that are way too loud with a straight-through muffler.


Lastly, the turbo-styled muffler utilizes a series of perforated pipes, chambers, and fiberglass to make the exhaust as quiet as possible. Because of the restrictions of flow found in these mufflers, they are generally not recommended for use in naturally aspirated engines, as these mufflers create considerably more backpressure.

Construction Materials

A muffler is constantly exposed to the elements and varying temperature cycles; therefore, a muffler needs to be made from durable, high-quality materials in order to last.

Most commonly, mufflers are made from aluminized or stainless steel. Aluminized steel being the cheapest of the two, does not resist corrosion as well compared to stainless steel.
