Specialist in exhaust technology:

We are Boysen

Boysen is a specialist in exhaust technology. At 23 sites worldwide, our 4,600 employees develop and produce exhaust manifolds, catalytic converters, particulate filters, silencers, trims and complete exhaust systems for cars, commercial vehicles and off-highway applications. The basis for our innovative approach is our headquarters - the development and administration centre at Altensteig in Baden-Württemberg, Germany.

Our major customers include the German vehicle manufacturers Audi, BMW, Daimler, Porsche and VW, the English brands Bentley and Rolls Royce and the commercial vehicle manufacturers Daimler and MAN.

Alongside our development expertise, one of the key features of our operations is that we are able to offer just-in-sequence (JIS) production and delivery of complete exhaust systems. As a system partner to the automotive industry, we are well aware of our customers' increasing requirements. We are deeply involved in all processes, continuously optimise our internal procedures and demonstrate our great strength when it comes to combining specialist knowledge with imagination. This is the only way to deliver tailored solutions that look to the future and provide our partners with crucial competitive advantages.

Linked to this is a clear performance promise:
