These Akrapovic Racing and Evolution exhaust systems have been designed especially for Super Duke riders who want to tease even more out of their bikes. The complete package delivers an optimised torque curve to the rear wheel and saves a lot of weight. This makes the Super Duke a shade more manoeuvrable. Not to mention the impressive workmanship and the supreme sports appearance: the new silencer design from Akrapovic is perfectly suited to the aggressive appearance of the Super Duke. The difference between Racing and Evolution silencers lies in the materials used: the Racing version is made from high-quality stainless steel, while a special titanium alloy is used for the Evolution. The performance characteristics of the two systems are identical. Both header pipes are prepared for the use of lambda sensors. The silencer end cap is made of carbon. The result is impressive: 9 kg less weight plus significantly more power and torque.
