Boysen stands for outstanding products

As a system partner and OEM, we have a day-to-day obligation to some of the world's leading automotive manufacturers. But the highest demands are those we set ourselves. Boysen brand products stand for optimum quality and endurance. Our exhaust engineers do everything they can to perfectly optimise performance and acoustics in a limited installation space.

As an exhaust system specialist, Boysen produces manifolds, catalytic converters, particulate filters, silencers, exhaust flaps and trims. Complete exhaust systems for high-quality cars, commercial vehicles and off-highway applications are at the upper end of our technological know-how.

Within the scope of the technological shift within the automotive industry, we also manufacture completely new product groups for vehicles – regardless of the drive system.
