The Akrapovic SLIP-ON SP series is a new addition to our product range. The attributes of the Akrapovic system work exceptionally well with the Kawasaki Z 750, making it a great combination of price, performance (107 HP) and quality materials. The system is made of high-quality stainless steel and titanium (muffler outer sleeve). A further feature of Akrapovic SP series exhaust systems is that they are officially approved for street use.
