The “Flowmaster Sound” is the true tone of American muscle and performance. Available in a wide range of domestic and import applications for automobiles and trucks, Flowmaster mufflers produce more power than Original Equipment (OE) and competitive aftermarket products. What makes Flowmaster so unique is that its performance improvement is paired with its unique exhaust tones. The “Flowmaster Sound” is offered in many different tones depending upon the muffler series. From the deep, aggressive tone of the Super 44™ to the quiet and subtle, but unmistakably rich Flowmaster tone of the 70 Series™, our family of mufflers offer the right application of performance and sound you want.
