Flowmaster Overview:
Today, Flowmaster, Inc. is housed in two ultra-modern U.S. facilities together totaling over 400,000 sq. ft. Flowmaster operates the only exhaust Research & Design facility of its kind in the world. Through use of dynos, Flowmasters 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 it currently offers, both for peak performance and just the right sound levels and tones.
