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 chassis dynamometers.
Measurements of the Akrapovic SLIP-ON system on the HONDA CBR 1000 RR (without muffler insert):
Power & Torque: The SLIP-ON system offers a performance increase throughout the entire rpm range. At 12450 rpm we measured 168.9 HP. The situation for the torque curve is similar, with the best results coming in the middle of the range around 4000 rpm, where the dropout in the stock curve is filled.
