Flowmaster operates the only exhaust Research and Design facilities of its kind in the world and is centered on the Superflow SF-7100 engine dynamometer complete with engine cycle analysis equipment and the SuperFlow Chassis dyno. Through this dyno, the brand’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 the induction to the tip of the exhaust system, while also showing the power numbers that really matter, the power numbers to the ground.
