Akrapovic Racing Exhaust System Suzuki Hayabusa The Akrapovic Racing Line has been designed specifically for demanding riders and represents an ideal balance between price and performance. The exhaust systems are dramatically lighter compared to stock exhaust systems and feature exceptional production quality and increased engine performance combined with pure racing sound output. The headers and mid-pipes are constructed of high-quality stainless steel conical tubes with precision handcrafting. A special process known as hydroforming is used in the manufacturing of the exhaust pipes. This process injects pressurized water into each tube to form the ideal shape for optimum exhaust flow without causing creases or compromising the strength of the steel. Akrapovic Exhausts unique design enables them to obtain the maximum output for each specific model of motorcycle, while significantly reducing overall weight. Its not just about peak power - Akrapovic exhaust systems deliver increased performance throughout the entire RPM range. Increased power and torque result in a much smoother ride. All Akrapovic exhaust system measurements are formulated on in-house computer-controlled flow benches. The Racing Line is identical to Akrapovics top range Evolution Line exhaust systems, with the major difference being the material that is used for the headers and mid-pipes. The headers and mid-pipes of the Evolution Line are constructed exclusively of titanium while the Racing Line uses stainless steel.
