Akrapovic Evolution exhaust system are designed for riders who know who to take full advantage of the specific performance benefits offered by these systems. This generally refers to professionally oriented riders. We should especially mention the Akrapovic Hexagonal mufflers, which with their carbon-fiber outlet caps match the design of the Honda exceptionally well.
Measurements of the Akrapovic system on the Honda CRF250R:
Power and Torque: the single muffler version delivers a performance increase mainly in the middle of the rpm range and at the top end and over-rev. Good riders will know how to make the most of the advantage.
