Video: Flowmaster Introduces New Street Mufflers And Explains Tech

When it comes to mufflers, Flowmaster has consistently been a brand of choice for enthusiasts, backyard-builders and professional shops for decades. Celebrating their 30th anniversary, they definitely deserve the attention. Afterall, where would many of our favorite racetracks and sanctioned races be without their continued support.

If you weren’t aware, “Flowmaster mufflers were conceived as a solution to a growing problem with sound issues at race tracks in California and beyond. In a successful effort to quiet racecars without reducing performance, our founder refused to accept the status quo of the day and instead pushed exhaust technology beyond common thinking. This led to many ‘firsts’ in automotive exhaust science, as well as many patents protecting the various technologies used in Flowmaster products. With those developments, Flowmaster ushered in a revolution in automotive performance exhaust,” according to the Flowmaster website.

To expand its line of products, Flowmaster is now developing and producing its own complete line of short- and long-tube headers as well as high-performance catalytic converters for many early and late-model vehicles.

In an effort to shed some light on the otherwise, underground scene of mufflers and muffler design technology, we’ve got some Flowmaster videos to help explain the process. For the muffler-conscious, Flowmaster has created a complete line of muffler in a variety of sizes, dimensions and even custom-tailored a unique sound from each of the different mufflers. Flowmaster has essentially removed the guesswork from choosing the correct muffler for you specific application. Whether you drive a truck or car and power it with a traditional small-, big-block or late-model power, this means you’ll be assured of the perfect tone.

We’ve highlighted three of Flowmasters mufflers unique below. Depending on your choice of sound, Flowmaster muffler series can provide your ride with mild, moderate, aggressive or a very aggressive sound level. It’s also important to note: all Flowmaster Stainless Steel mufflers come with a Lifetime Limited Warranty. If you don’t find what you are looking for or just unsure of your choices, call the Flowmaster Muffler technical support department at (707) 544-4761.
