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 flow and the intended power, performance development. CNC-machined components and welds that do not reduce the inner diameter play a crucial role. 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 ignition sequence, the optimal layout of the header, connectors, and mid-pipes right through to the silencers is developed in countless test bench runs.

Arrow headers are made from a special steel alloy (racing variants also from high-quality, lightweight titanium). The 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 header 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 available in the range.

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