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 YAMAHA YZF R6 (without muffler insert):
Power & Torque: the R6's engine spins more freely with the Akrapovic Slip-On system, which is reflected in the power and torque curves. The amount of increased power expands as you go up the rpm range, so that at 14560 rpm the rear wheel puts out 112.9HP. Max. increased power of 1.2 HP was measured at a screaming 14580 rpm.
