General description

A passion for great sound and a wide range of models – that's what Arrow stands for. With extensive know-how gained from years of data collection and collaboration with racers from MotoGP, WSBK, and other classes, Arrow exhaust systems are continuously developed and optimised in line with technological advancements and current trends.

Collectors and tubes are key to optimal exhaust gas routing and the intended power, performances development. CNC-machined components and welds that do not reduce the internal diameter contribute significantly to this. Thus, the diameter of the tubes, bend radii, welds and their exact placement and execution, as well as the guide of the header pipes, are optimally adapted to each bike. Depending on the engine and firing order, the optimal layout of the header, connecting pieces and intermediate pipes up to the rear silencers is developed through countless dyno runs.

Arrow headers are made from a special steel alloy (racing variants also from high-quality, lightweight titanium). V2A steel is highly temperature-resistant and can be mechanically formed very well. It has high resistance to humidity, water, and weak alkalis, as used in motorcycle care products. Due to its lower weight, the titanium header variant is used in racing.

Features:
- Flow-optimised
- Optimal power, performances development
- Available for numerous models
