Overview of Akrapovic Stainless Steel/Titanium Evolution Line Exhaust System w/BN Muffler - S-Y4MR13-BNTA

A complete high-quality exhaust system made from stainless steel tubes and a titanium muffler outer sleeve with precision handcrafting and attention to detail. Its unique design yields the maximum output for each specific motorcycle model while significantly reducing overall weight for top performance. It's identical to our top-range Evolution Line exhaust system. The only difference is in the material used.
Our 2013 exhaust systems meet new FIM 2013 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.

  • Same as the Evolution system, only constructed with stainless steel
  • Connected with a sleeve joint held together with a silicon-shielded tensioning spring
  • 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 is welded to the muffler
  • Inlet cap and inner perforation are made entirely out of titanium
  • Carbon-fiber heat shield included where needed
  • Laser-engraved spark arrestor in certain models
  • Yamaha YZ450F muffler has an additional chamber for better torque and throttle response with less sound

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 made on our computer-controlled flowbenches.
