From turbo flange to rain flap


As a system supplier for complete ex­haust systems, we are happy to supply you with the necessary pipes for the in­te­gra­tion of our ex­haust purification pro­ducts and silencers. We have the tech­ni­cal capability to pre-assemble entire ex­haust pipe systems, from turbo flange to rain flap, in accordance with your spe­ci­fi­ca­tions and de­liver them to you as ready-to-install components.

Naturally, we are also happy to pre-as­semble pipes for inter­cool­ers, coolant circuits or fuel supply lines.

When corresponding loads are applied to engines, the exhaust pipes can quickly reach temperatures of more than 100°C. As engine com­part­ments become in­crea­sing­ly compact, the radiant heat from ex­haust pipes can quickly cause prob­lems for other, more heat-sensitive com­po­nents installed around the engine. On the other hand, newer motors that are already equipped with an emission con­trol system ex-works re­quire cer­tain mi­ni­mum exhaust temperatures in the par­ti­cu­late filter system or the SCR ca­ta­ly­tic converter in order for these com­po­nents to work properly.

For applications that require specific tem­­pe­ra­tur­es, we offer exhaust pipes with permanently installed integral in­su­la­tion. Despite the thinness of the in­su­la­ting material, this in­su­la­tion pre­vents ra­diant heat while at the same time main­tain­ing the necessary exhaust tem­pe­ra­tu­res for the emission con­trol com­po­nents in the exhaust system to work pro­per­ly. The high-strength stain­less-steel film used for the outer lining is wa­ter-, fuel-, oil-, urea- and acid-re­sis­tant.



  • Extremely stable and vibration-resistant integral insulation for per­ma­nent heat insulation of exhaust pipes
  • Can be applied to any pipe shape or design
  • Excellent insulation at temperatures of up to 1,100 °C despite low ma­te­rial thickness
  • Waterproof
  • Fuel-, oil-, urea- and acid-resistant thanks to the stainless-steel outer li­ning
