Akrapovic Full Exhaust Approved A6R4-HAPC Carbon/Steel Aprilia RS 660

Designed to optimize the power and torque of the 660cc parallel twin engine, this system meets EC/ECE approval, making it fully Euro 5 compliant. With the catalyst positioned at the front of the pre-muffler, to ensure full system compliance to the regulations, the system has a plug-and-play installation without the need for remapping. Constructed from premium carbon fiber, lightweight titanium and premium stainless steel, the system was created using race-proven materials. Designed to emphasize the racing look of the car, the system is 0.4kg lighter than standard stock. Tests on the internal Akrapovič test bench, in consecutive runs of motorcycles equipped with Racing Line (Carbon) exhaust and standard exhaust system, recorded an increase of 2.4 HP at 11,200 rpm and a gain of 3.6 Nm of torque at 4.550 rpm, which offers the rider a pronounced throttle response. Its deep, full and sporty sound, with its throbbing parallel twin pulsations, offers the sensation of riding a larger displacement motorcycle, making the Akrapovič Racing (Carbon) line for Aprilia RS 660 the ideal exhaust for this mid-displacement sports bike .
