Akrapovič's manufacturing expertise and the passion of the Ducati technicians are brought together in this complete racing exhaust system made entirely of titanium. This system can withstand high temperatures and complies with the noise limit required on track at a standstill with an exhaust sound level of less than 105 dB @5500 rpm, according to the FMI CIV SBK regulations. It's made of a special titanium alloy, which further lightens the bike, improving the power-to-weight ratio for consistently excellent performance. It features a racing-derived polyester air filter, which, besides being more permeable, also guarantees excellent filtering power and easy maintenance. The map provided as standard adapts all the DTC - DWC - DPL and DSC control parameters to the bike's new performance levels, and the careful torque and power work have led to improvements across the Streetfighter V4's entire range of use. Aesthetically, the dual under-seat silencer makes the bike design even more unique, giving it an additional aggressive touch, which is completed by its unmistakable sound.
