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 delivery. CNC-machined components and welds that do not reduce the inner diameter contribute significantly to this. Thus, the diameter of the tubes, bending radii, welds and their precise 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, connecting pieces, and intermediate pipes, right through to the silencers, is developed through countless dyno runs.

Arrow manifolds are made from a special steel alloy (racing variants also from high-quality, lightweight titanium). The V2A stainless steel is highly temperature-resistant and very easy to mechanically form. It possesses high resistance to humidity, water, and weak alkalis, such as those 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. Aftermarket catalytic converters are also available for exhaust gas purification.

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
