    • Today, Flowmaster, Inc. is housed in three ultra-modern facilities together totaling over 400,000 sq. ft., one in Santa Rosa, one in West Sacramento, California and the other in Hayden, Idaho. Flowmaster employs over 250+ workers dedicated to building the highest quality U.S. made exhaust products available.

    Flowmaster operates the only exhaust Research and Design facility of its kind in the world, centered around our SuperFlow engine dynamometers complete with E.C.A. (engine cycle analysis) equipment and also SuperFlow chassis dynos. Through use of these dynos, Flowmaster's engineering staff can track the complete engine cycle in millionths of a second and can obtain exact technical data of each degree of cam rotation, from induction to the tip of the exhaust system, while also showing the power numbers that really matter, the power numbers "to the ground." Flowmaster also utilizes Spectrum Analyzers to fine "tune" the sound of each of the eleven different series of mufflers that Flowmaster currently offers, both for peak performance and just the right sound levels and tones.

    Flowmaster's product line includes exhaust products for Performance Street, Muscle Cars, Trucks, Street Rods, RV's, Motorhomes, and all types of race applications. With over 400 different muffler models, 370+ exhaust systems and numerous exhaust accessories available, Flowmaster offers you the choice of sound to fit your preference from "wild to mild" and your specific vehicle needs. With Ray still active and "hands on" with the R and D department in the development of new exhaust products and new technologies currently being tested, the future looks to be very exciting indeed.
