For the Yamaha R1 we present a basic version of the Akrapovic SLIP-ON exhaust system with two mufflers and two link pipes. We have also developed an extended version with an optional Y- connecting tube. The basic Akrapovic SLIP-ON system allows the use of the stock catalytic converter. The version with the optional Y- connecting tube extends past the point where the catalytic converter is located, so that the catalytic converter is removed. There is no major difference in performance between the two systems. However, they both outperform the stock system in both power and torque. The system is intended for riders who do not wish to make major exhaust system modifications.
Power & Torque: performance measurements were made on both systems. The difference is minimal, with the advantage going to the option with the optional Y-connecting tube, which is slightly better in the middle of the rpm range. There is also a slight difference at the top end, but this does not affect the riding characteristics. Despite being only a first-stage tuning component, the system adds quite a bit of power to the stock engine figures. The standard option without the Y-connecting tube puts out 159.6 HP at 12800 rpm. The option with the optional Y-connecting tube was measured at 159.4 HP at 12700 rpm. The torque curves of the two options are also very similar. There is a significant increase over the stock torque curve, especially above 6000 rpm.
Akrapovic was founded in 1991 and rapidly gained recognition in the competitive racing scene, securing its first Superbike SBK victory in 1997. In 1999, the company expanded its operations to boost production capacity and deliver top-tier performance exhaust systems. By 2000, Akrapovic had claimed the SBK World Championship title and made its debut in the MotoGP series in 2002. A titanium foundry was established in 2009, followed by the inauguration of a second production plant in 2014. Further advancements in exhaust system production were introduced in 2015, leading to the achievement of over 100 world titles across motorcycle and car racing championships. Today, Akrapovič stands as a premier manufacturer of high-performance exhaust systems for motorcycles and cars, known for its cutting-edge technology and commitment to using premium materials. With a workforce exceeding 1,600 and operations in more than 80 countries, Akrapovic provides technical support to top-tier racing teams, including MotoGP, WorldSBK, MXGP, and IMSA WTSC. All exhaust systems are fully produced in Slovenia. Road-approved sports exhausts are clearly marked in their descriptions and come with a certificate for registration purposes. Most Akrapovic exhaust systems are custom-built, so it's recommended to reach out in advance for details on production and delivery times.
