Boysen (1895 - 1975) is considered one of the pioneers of modern silencer technology. With his experiments in the fields of acoustics and fluid dynamics, he was the first person to recognise the influence of exhaust gas routing on the charge cycle, engine power and torque progression. Boysen's test rig for exhaust silencers underlines his pioneering work - it was the first of its kind in the world. Every Boysen employee has the motivation to apply their knowledge and ability in development, testing, production and logistics in practice. We employ flexible thinking, pragmatic action and short decision-making processes. For fast, targeted results that set new standards. Personally, I have decided on catalytic converters because they have shown the best results to date and catalytic converters can be installed in a standard exhaust system economically. This was Friedrich A. Boysen's response in a TV interview on 8th January 1965, when asked which form of exhaust gas detoxification he believed would have the greatest success. Just ten years later, catalytic converter technology was used in the USA for the first time. FRIEDRICH A.
