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, advancing with technology and adapting to current trends.



Collectors and tubes are key to optimal exhaust gas flow and the intended power, performance delivery. CNC-milled components and welds that do not reduce the internal diameter contribute significantly to this. Thus, the diameter of the tubes, bending 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 firing order, the optimal layout of the header, connectors, and mid-pipes right through to the silencers is developed over countless dyno runs.



Arrow headers are manufactured from a special steel alloy (racing versions also from high-quality, lightweight titanium). V2A stainless steel is highly temperature-resistant and very malleable. 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. Aftermarket catalytic converters are also available for exhaust gas purification.



Features:

- Manufactured from stainless steel or titanium (0.8 mm wall thickness)
