Here is the complete URBAN exhaust line from the famous ARROW brand, specially designed for your KYMCO AK 550 maxi scooter from 2017 to 2020.
The design of its URBAN silencer is developed with aesthetic consideration and technical finesse. The high quality aluminum used ensures both lightness and corrosion resistance.
The internal design of the silencer is designed to optimize the exhaust flow, reconciling performance and compliance with noise standards*.
The black external coating adds a personalized visual touch to your maxi scooter.
The URBAN muffler is designed to improve exhaust flow, allowing the engine to breathe more freely. This can result in a slight increase in power and torque, while maintaining a controlled sound.
Its connection**, manufactured with precision to optimize the performance of your machine, offers smoother gas evacuation, thus releasing all the power.
The design is designed to maximize airflow, reduce back pressure and deliver deep resonance. Its stainless steel construction guarantees lightness and robustness, two crucial characteristics for any speed enthusiast.
It is offered in a catalyzed version, less polluting and approved, or in a decatalyzed version, freer, more efficient but not approved.
Its racing collector*** made with high quality materials such as stainless steel, is designed to be light, durable and offer better circulation of exhaust gases.
Great attention to detail has been paid, optimizing the manifold design to maximize exhaust gas flow while minimizing restrictions. This results in increased engine power, better throttle response and improved exhaust sound.
In summary, this line is an elegant combination of careful design, quality materials and advanced technologies to offer both distinctive style and optimized performance to your maxi scooter.
The collector is interchangeable with the original one.
