Overview of success factors

  • Significant advantages

    Motorcycle manufacturers can save time and money by giving WP the overall assignment for complete exhaust systems. The production machinery is  constructed internally, saving production time and reducing tool expenditure. In addition, any alterations necessary during production lead-times – or at a later date - can be quickly implemented. Constructive overall solutions are possible, for example by integrating a Lambda probe in the manifold or the assembly of various components including the heat protection shield. The entire processing of the manifold  takes place under one roof and, due to an 80% degree of automation, it is possible to produce a large number of units with relatively low piece costs. At the same time we achieve the minimal production tolerance specified by the manufacturer and perform a final100% inspection of all the connecting dimensions, so the final assembly of the exhaust manifold is a quick process.

  • Top performance

    WP exhaust manifolds are essential for tuning the exhaust system to the engine’s characteristics, for spontaneous engine response and a maximum output, at the same time adhering to the noise and exhaust emission regulations. For this reason, WP implements the latest technology in producing exhaust manifolds with the best possible performance and fitting accuracy – technology such as WIG/MAG robotic welding, automatic welding machines, plasma cutters, WIG/MAG manual welding, thermoforming, punching and CNC tube bending.

  • Better– from WP

    More compact and complex construction methods are possible due to using a tighter bending radius than other manufacturers. We use only materials and suppliers of the highest quality, therefore guaranteeing long durability and constant engine output throughout the entire driving cycle. In contrast to other suppliers, our pipe-welding methods safeguard against a burn-through which, although outwardly invisible, would influence the flow through the exhaust manifold and have a detrimental effect on the motorcycle’s output. The surface and intersection welding are of such high quality that no extra parts are necessary to improve the appearance.
