The Akrapovic Evolution Exhaust system is constructed entirely of titanium and is the flagship of the Akrapovic line. Developed by the same group of engineers who work with championship-winning race teams in World Motocross, Supercross and World Enduro Classes and armed with the feedback provided by champions like Ryan Dungey and Antonio Cairoli, Akrapovic has designed their exhaust systems to deliver increased performance throughout the entire RPM range. Increasing power and torque throughout the entire RPM range offers a much smoother, controllable power delivery and is key for maximum performance and handling.
