General description

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 play a significant part in this. The diameter of the tubes, bend radii, welds and their exact placement and execution, as well as the guide of the manifold pipes, are optimally adapted to each bike. Depending on the engine and firing order, the optimal layout of the manifold, connectors, and intermediate pipes, right through to the silencers, is developed over countless test bench runs.

Arrow manifolds are made from a special steel alloy (racing versions also from high-quality, lightweight titanium). V2A steel is highly temperature-resistant and very malleable. It has high resistance to humidity, water, and weak alkalis, as used in motorcycle care products. Due to its lower weight, the titanium manifold variant is used in racing.

For legal operation, a version with an integrated catalyst is also available for many motorcycles. Retrofit catalytic converters for exhaust gas purification are also part of the range.

Features:
- Made from stainless steel or titanium (0.8 mm wall thickness)
- Flow-optimised
- Optimal power, performances development in conjunction with various silencer variants
- Available for numerous models
