Akrapovič S-A6R4-HAPC Racing Line Carbon Full Exhaust System Aprilia Rs 660 2021 - 2024

Designed to optimise the power and torque of the 660cc parallel twin engine, this system meets EC/ECE homologation, making it fully Euro 5 compliant. With the catalytic converter positioned at the front of the pre-muffler to ensure the system is fully compliant with the regulations, the system is a plug-and-play installation with no remapping required. Constructed from high-grade carbon fibre, lightweight titanium and premium stainless steel, the system has been created using race-proven materials. Designed to emphasise the racing look of the machine, the system is 0.4 kg lighter than the standard stock system. Testing on the Akrapovič in-house dyno, in consecutive runs of bikes fitted with the Racing Line (Carbon) exhaust and the 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, giving the rider a pronounced throttle response. Its deep, full and sporty sound, with its throbbing twin parallel pulses, gives the sensation of riding a larger displacement motorcycle, making the Akrapovič Racing Line (Carbon) for the Aprilia RS 660 the ideal exhaust for this mid-displacement sports bike.
