Our sporty and lightweight SLIP-ON STREET LEGAL systems offer a great balance between price and performance and represent the first step in the exhaust system tuning process. The change will also be visual as our HEXAGONAL muffler perfectly fit the exterior line of the Multistrada and add a clean racing image. The striking muffler with titanium muffler outer sleeve and carbon fiber outlet cap perfectly complements the lines of the bike. The Slip-On system is legal for street use.   Performance   Measurements of the Akrapovic SLIP-ON STREET LEGAL system on the Ducati Multistrada:  Power & Torque: the exhaust system modification with the SLIP-ON STREET LEGAL system results in a major boost in performance, delivering a massive 140.8 HP at 9270 rpm on back wheel.
