For the Yamaha R1, the Akrapovic Slip-On exhaust system includes two mufflers and two link pipes. We have also developed an extended version with an optional Y- connecting tube. The basic Akrapovic Slip-On system allows the use of the stock catalytic converter. The version with the optional Y- connecting tube extends past the point where the catalytic converter is located, so that the catalytic converter is removed. There is no major difference in performance between the two systems. However, they both outperform the stock system in both power and torque. The system is intended for riders who do not wish to make major exhaust system modifications.
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.
