Overview of Akrapovic Titanium Evolution Line Exhaust System - S-Y4MET13CIBNTA

The flagship of the AkrapoviC exhaust system range, used and tested by our top factory teams in motorcycle racing. It's simply the finest exhaust system available. Each model is unique and dedicated to maximizing the engine's performance, while reducing overall weight for optimized overall handling of the motorcycle. It is made entirely of titanium. Exhaust systems meet FIM noise limits, feature a more durable welded bracket and titanium end cap. Performance exhaust systems also feature a new coating for the silencer outer sleeve giving better scratch resistance and easier cleaning.

  • Flared or conical link pipe is made of titanium and welded to the muffler
  • New BN muffler design meets FIM 2013 noise limits
  • Hexagonal mufflers feature a composite plastic outlet cap to match the design of each bike; BN mufflers use a titanium end cap
  • Link pipe; header tube joint is milled on a state-of-the-art CNC machine and secured by high-quality, silicon-shielded tempered springs
  • Conical shaped header tube is made of titanium
  • Ceramic anti-seizing grease is used to prevent seizing, corrosion and excessive wear of parts of the exhaust system made of titanium (due to vibration and extreme temperatures)
  • Carbon-fiber heat shield included, if called for in the design
  • Yamaha YZ450F muffler has an additional chamber for better torque and throttle response with less sound
