Akrapovic Slip-On Line (SP Series) Titanium Mufflers for Yamaha YZF R1 (07-08)

Akrapovic SLIP-ON represents an initial move in the direction of tuning and is intended for drivers, which do not desire fundamental changes in the area of the exhaust system. We offer two options of the SLIP-ON system for the Yamaha R1: the standard Slip-On and Slip-On SP Series. Both are facilitated by the use of the stock catalyst as the system does not interfere with the catalytic converter set up. In terms of performance measurements, the two types do not differ much. Their advantages can be illustrated in comparison with a serial exhaust system, since the increase of power and torque based on smaller modifications on the exhaust system relatively large. With the use of the catalytic converter the Slip-On and Slip-On SP series are available also in a street legal version.

Measurements of the Akrapovic SLIP-ON system on the YAMAHA YZF R1:

Power & Torque: measurements for both options of the exhaust were prepared. 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 generator. At 12500 rpm, we measured 167 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 5000 rpm, in which range the motor gains the most.

We offer two options of the Akrapovic SLIP-ON exhaust system for Yamaha R1: the standard Slip-On and the SP Series Slip-On. In both cases the system is composed of two mufflers, the difference being only the used materials and the design. Slip-On has mufflers (outer sleeve) made from titanium or carbon, the SP series only from titanium. In both cases, the mufflers are attached beneath the seat of the motorcycle by carbon clamps. Link pipes are made from titanium (SP series from stainless steel), cylindrical and welded to the mufflers. The joining of the link pipes with the stock header assembly was executed with a sleeve joint, the strength of the joint is provided by a metal clamp. The system retains the stock catalytic converter of exhaust gases. The following systems are available in this configuration: Slip-On open, Slip-On Street Legal, Slip-On SP series open, Slip-On SP series homologated.
