This updated design uses race-proven materials in the construction of the system, with a high-quality lightweight titanium link pipe, titanium inner muffler structure and new style tip, all combined with a carbon fiber outer muffler sleeve, which has created an exhaust that is over 23% lighter than the standard stock version. A full, intense sound is emitted when the machine is idling, providing a deep, full sound with distinctive AkrapoviÄ character when you''re on the move.
