Designed to optimize power and torque from the 660 cc parallel-twin powerplant, this system meets EC/ECE type approval, making it fully Euro 5 compliant. With the catalytic converter located in the front part of the pre-muffler, to ensure the system fully complies with the regulation, the system has a plug-and-play installation with no remapping needed. Constructed from high-quality carbon fibre, lightweight titanium, and high-grade stainless steel, the system has been created using race-proven materials. Designed to emphasize the racing look of the machine, the system is 0.4 kg lighter than standard stock. Testing on the Akrapovič in-house dyno, in back-to-back runs of bikes equipped with a Racing Line (Carbon) exhaust and standard stock 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 gives the rider a pronounced throttle response. Its deep, full, and sporty sound, with its throbbing parallel-twin pulsations, offers the feeling of riding a bigger capacity bike, making the Akrapovič Racing Line (Carbon) for the Aprilia RS 660 the ideal exhaust for this middleweight sports bike.
