Manufacturer Info![]()
Flowmaster Inc. is a well known manufacturer of high performance mufflers and complete exhaust systems with more than 22 years of excellence in the exhaust aftermarket. Back in the early 80’s founder Ray Flugger created his famous “Suitcase” racing mufflers based on creative ideas and strong engineering principles. These innovative new mufflers resulted from thousands of hours of Dyno research and on-track testing around the country.
As company President and Founder, Ray Flugger, worked his magic producing more horsepower for many kinds of racing engines while at the same time lowering exhaust sound levels. It is through this extensive testing and dedication to the sport that Flowmaster has been able to help in the preservation of race tracks throughout the country. Flowmaster’s role has been to develop products that help make racing events produce acceptable sound levels within its community, despite their proximity to homes and businesses.
Flowmaster, Inc. is housed in an ultra-modern 100,000 square foot facility in Santa Rosa, and a 300,000 sq. foot facility in Sacramento, California, employing 300+ dedicated workers. Flowmaster operates the only exhaust research facility of its kind in the world, centered around the Super Flow SF-7100 engine dynamometer. Through use of this state-of-the-art Dyno Flowmaster’s engineering staff can track the complete engine cycle in millionths of a second and can obtain exact readings of each degree of cam rotation, from induction to the tip of the exhaust system.
Through continuous product testing and development the Flowmaster product line has expanded rapidly over the past fifteen years from its original roots in racing to further include exhaust products for performance street, truck, RV and motorhome applications. With over 400 different muffler models and 140+ exhaust systems available Flowmaster offers you the choice of sound to fit your specific vehicle.
