Flowmaster

Flowmaster operates the only exhaust Research & Design facilities of its kind in the world, centered around the SuperFlow SF-7100 engine dynamometer complete with E.C.A. (engine cycle analysis) equipment and also SuperFlow chassis dyno's. Through use of these dyno's, 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 Flowmaster currently offers, both for peak performance and just the right sound levels and tones.

Flowmasters 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 sound preference from "wild to mild" and of your specific vehicle needs.
