Measurements of the Akrapovic SLIP-ON system + Y link pipe on the YAMAHA YZF R1 shows there is a minimal difference between the two options. Both exhaust options obtain a somewhat better result in the lower and particularly in the middle range of rpm. Despite the initial level of tuning, the system can substantially upgrade the serial release of power from the engine. At 12500 rpm, we measured 168,7 HP at the back wheel (both options). The systems do not differ much in terms of torque either. The upgrade of a serial torque is nicely evident particularly between 3200 rpm and 6500 rpm, in which range the motor gains the most. With our system you will also save more than 3 kg, compared to stock exhaust.
