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, performance delivery. CNC machined components and weld seams that do not reduce the internal diameter contribute significantly to this. Thus, the diameter of the tubes, bending radii, weld seams, 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, connecting pieces, and link pipes up to the silencers is developed through countless dynamometer runs.

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

For legal operation, a version with integrated catalyst is also available for many motorcycles. Aftermarket 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, performance delivery in conjunction with various silencer variants
- Available for numerous models
