The new Akrapovic Racing Line exhaust allows the 847cc Yamaha engine to breathe and deliver increased levels of performance (5.4bhp/ 9900rpm) and torque 5.3Nm (3.9ft-lb) / 5000rpm, a deep resonant exhaust tone and of course lighter weight, that is 2.4kg (5.3 lbs). 
Constructed in two sections for ease of fit, the front section consists of three manifold tubes.

Even though the exhaust increases performance and throttle response, there is no need for additional tuning providing the original Yamaha lambda sensor is retained – provision for this is provided on the collector tube. The exhaust is EC-Type approved with the optional Akrapovic catalyzer mounted.
