Racing Line Exhaust System

Designed to optimise the power and torque of the 660 cc parallel-twin engine.  
With the catalytic converter positioned at the front of the pre-muffler to fully comply with regulations; plug-and-play installation with no need for remapping.  
Manufactured from high-quality carbon fibre, lightweight titanium and premium stainless steel, using materials proven in competition.  
Designed to enhance the bike’s racing look, the system is 0.4 kg lighter than the original.  
Dyno tests at Akrapovic, comparing Racing Line (Carbon) and original exhausts, recorded an increase of 2.4 hp at 11,200 rpm and a torque gain of 3.6 Nm at 4,550 rpm, significantly improving throttle response.  
Its deep, full and sporty sound, with characteristic pulses of the parallel-twin engine, delivers the feeling of riding a larger-capacity motorcycle, making the Akrapovic Racing Line (Carbon) for the Aprilia RS 660 the ideal exhaust for this mid-range sports bike.
