Akrapovic Racing Exhaust System Yamaha MT-09 / SP
Akrapovic is proud to introduce a stunning Racing Line exhaust for the Yamaha MT-09 The MT-09 is a bike with a strong focus on riding emotion and represents a new direction in sport-bike evolution. A bike designed to give homage to the darker and unconventional side of Japanese society can now be made even more mean, moody, and exciting with the addition of Akrapovic’s offering.
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 than 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 unique process known as hydroforming is used to manufacture 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 Exhaust’s unique design enables them to obtain the maximum output for each motorcycle model while significantly reducing overall weight. It’s 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 Akrapovic’s top-range Evolution Line exhaust systems, with the significant difference being the material 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.
