General Description

Passion for great sound and a wide range of models – that's what Arrow stands for. With extensive expertise gained through years of data collection and collaboration with racers from MotoGP, WSBK, and other classes, Arrow exhaust systems are continuously developed and optimised, keeping pace with technological advancements and current trends.

Collectors and tubes are key to optimal exhaust gas flow and the intended power, performance 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, connection pieces, and intermediate pipes up to the rear silencers is developed through countless dyno runs.

Arrow headers are manufactured from a special steel alloy. The steel is highly temperature-resistant and very malleable. It has high resistance to humidity, water, and weak alkalis, such as those used in motorcycle care products.

Features:
- Flow-optimised
- Optimal power, performance development in conjunction with various rear silencer variants
