Flowmaster is committed to continually developing high quality, performance products that work with a wide variety of applications. Designed to meet the specific needs of street, race and utility vehicles, our products share one common challenge: to improve internal combustion engine efficiency.For more than 28 years, Flowmaster has been the leader in advanced exhaust technology through our extensive commitment to research and development. We learned early on that by understanding an engine’s total operation, including the exhaust pressure pulses, sound waves and the heat energy they contain, we could not only generate a terrific performance exhaust sound, but more importantly increase combustion efficiency and improve both performance and fuel mileage.These elements are at the core of our success and how we began the process of creating our innovative muffler and exhaust system designs.Race MufflersResonant tuning chamberDelta flow technologyThermal barrierSuper 10 SeriesPRO Series
