Slip-Ons represent the first step in the exhaust system tuning process, and they offer a great balance between price and performance. Sporty and lightweight Slip-On Line exhaust systems are a perfect match for this great Aprilia. Installation is a snap. The visual change comes with stylishly shaped carbon fibre mufflers and end caps. In addition to design effects and improved power delivery, Slip-Ons also enhance the Aprilia sound. Let your bike stand out with more power, beautiful design, and the unique Akrapovič sound of Slip-Ons.
