General description

Passion for great sound and a wide range of models – that's what Arrow stands for. With extensive expertise 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 tube are key to optimal exhaust gas routing 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 tube, bending 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 headers, connecting pieces, and mid-pipes right up to the silencers is developed through countless dyno runs.

Arrow headers are manufactured from a special steel alloy. V2A stainless steel is highly temperature-resistant and very malleable. It offers high resistance to humidity, water, and weak alkalis, such as those used in motorcycle care products.

Features:
- Manufactured from stainless steel
- Flow-optimised
- Optimal power, performance development in conjunction with various silencer variants
- Available for numerous models
