Race-proven materials and sporty design have led to an exhaust that is the perfect introduction to the exhaust tuning process The carbon-fiber muffler outer sleeve and end cap are stylishly shaped for a visual impact, and the use of lightweight titanium for the link pipe and inner structure means this system weighs in at 3.5 kg lighter than stock, for an impressive savings of 62.4% This exhaust has been developed for use on closed-course competition circuits, and it delivers track performance to match that demand To match the performance and style, the Slip-On Line (Carbon) system serves up a deep and vivid sound, full of Akrapovic character, to totally encapsulate the Aprilia engine To obtain optimum performance, throttle response, and durability, remapping is recommended.
