Akrapovic sporty and lightweight SLIP-ON system offers a great balance between price and performance, and represents the first step in the exhaust system tuning process. The change will also be visual as our HEXAGONAL mufflers fit the exterior line of the R1 perfectly and add a clean racing image.

The muffler outer sleeve is made of titanium or carbon fibre, which gives a special hi-tech touch to our SLIP-ON system. We offer an optional Y type link pipe made of conical titanium tubes for more power and torque. You will also save up to 4.13 kg, compared to using a stock system. 

Measurements of the Akrapoviè SLIP-ON system on the YAMAHA YZF R1 (without a muffler insert):

Power & Torque: The exhaust system modification with the SLIP-ON OPEN + Y type link pipe system results in a major boost in performance, delivering a massive 164.2 HP at 12410 rpm on the back wheel. But the increased power is not available just at the top of the range; the system already exhibits its quality at 4800 rpm and up, through the entire rpm range. The maximum power increase between the Akrapoviè and the stock system is 5.1 HP at 6000 rpm. Additionally, the torque is substantially higher in the lower rpm area at 3000 rpm, and in the middle to high rpm area.

ALSO AVAILABLE: Full system for 2009 R1 and exhausts to fit earlier R1 models too. Please contact us for details.
