Yamaha YZ 250F 2010 Racing Exhaust System
 The Akrapovic Racing and Evolution complete exhaust systems are the championship winning flagships of our product lines. They are designed for competition-oriented MX riders who demand maximum performance from their exhaust systems, made of extremely durable high grade titanium. With their production quality, engine performance improvements, weight reduction and modern Hexagonal muffler design they satisfy even top pro racers. The systems are designed for two markets; in the USA they are available with an approved spark arrester, and for the EU and other non-US markets they come with a noise damper. Our patented additional chamber helps to reduce noise emission and provides better power and torque delivery. For the Racing system we use stainless steel tubes and composite end cap while we use titanium tubes and carbon-fiber end cap for the Evolution system
