PERFORMANCE
Measurements of the Akrapovic SLIP-ON system on the YAMAHA YZF R1 (without muffler insert):
Power & Torque: the exhaust system modification with the SLIP-ON OPEN system results in a major boost in performance, delivering a massive 163.9 HP at 12410 rpm on back wheel. But the increased power isn’t available just at the top of the range; the system shows its quality already from 5500 rpm up through entire rpm range. Max. increased power between the Akrapovic and the stock system is 2.4 HP at 12430 rpm. Besides this, the torque is substantially higher in a lower rpm area at 3000 rpm and from middle to high rpm area.
It’s not just about peak power—Akrapovič exhaust systems deliver increased performance throughout the entire rpm range. Increased power and torque result in a much smoother ride. All Akrapovič exhaust system measurements are made on our computer-controlled flowbenches.
