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, 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 weld seams that do not reduce the inner 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, connection pieces, and mid-pipes up to the silencers is determined through countless dynamometer runs.

Arrow headers are made from a special steel alloy (racing versions also from high-quality, lightweight titanium). V2A stainless steel is highly temperature-resistant and can be mechanically formed very well. 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 variant is used in racing.

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

Features:
- Made from 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
