Design. Special attention was given to themanufacture of our exhaust systems,materials were carefully selected andcarefully assembled, having in mind Yourbike is more than just a powerfullcompetition machine.

Performance. Countless hours werespent on the development of the geometryof the exhausts - on the dyno bench andtrack. Along that, careful manufacturingensures maximum performance out ofyour engine.

Advanced solutions. Attention was givento details; perfectly fitting CNC machinedheaders, with O-rings that ensure theabsence of oil leaks. While a well toughtsystem of spring removal makes amechanic’s life easier.

What more do exhaust system offer;- Wide product range, for many different engine blocks and specificcylinders.- High temperature resistant transparent laquer.- Special shape of exhaust flanges on some models.- Carbon fiber silencer, with sound absorbing glasswool wrappedaround perforated tube.- Available the normal and straight „sprint“ silencer.
