The Akrapovic Racing and Evolution open systems are designed for riders in road racing closed course competition and for those who attend trackdays and expect the maximum from their exhaust system. The Racing and Evolution open systems make the Suzuki substantially more responsive, and the HEXAGONAL muffler also provides a great visual modification and weight savings. Systems fit perfectly to stock mounting points and allow the use of passenger footpegs.
