Equipped with a Flowmaster exhaust system, your vehicle will get noticed wherever you drive. Designed to deliver maximum performance combined with the sound you need, all the exhaust systems have one thing in common - the quality. They are manufactured using the up-to-date equipment to reach the level of precision you deserve, and made from the top-quality 304 stainless steel to ensure the durability you can rely on.
The company offers five types of exhaust systems to meet your needs. The mildest tone is offered by the Force II system, which increases the performance and is not too aggressive for street driving. The dBX exhaust system is a perfect solution for the sport compacts and import vehicles. It offers a deeper tone and great acceleration sound. If you prefer something wilder, opt for Pro-Series exhaust. It features a deeper tone with aggressive sound characteristics.
What makes the Flowmaster mufflers unique is that their performance improvements are combined with the unmistakable sound. Some of the mufflers such as the Super 10 Series are so loud that they're not recommended for use on the street-driven vehicles, however for the racing applications they are a must. From the powerful and ruthless tone of the Super 44 Series to the quiet and pleasant yet rich tone of the 70 Series, you'll easy find something that will unleash the true character of your vehicle.
Flowmaster mufflers are manufactured using either a chambered or laminar muffler technology. The chambered mufflers feature the Delta Flow technology, which provides advanced noise cancellation, ensuring superior scavenging of exhaust gases. The laminar mufflers are the latest generation in the Flowmaster family. They accelerate the exhaust flow as it passes through the tapered core and expands into the outer core areas, which improves performance and delivers a deep mellow exhaust tone.
