Akrapovič Racing Exhaust in Carbon for Yamaha MT 03 320 (16-26), YZF R25 (14-24), YZF R3 (15-26) S-Y3R3-APC

The Akrapovič Racing Line (Carbon) full exhaust system is intended for Yamaha MT-03 320 and YZF-R25/R3 motorcycles, depending on model and year. It replaces the standard exhaust to deliver a sportier response and a racing sound.

• Carbon fibre components: muffler outer sleeve and end cap.
• Lambda sensors: compatible with M12 and M18 sensors.
• Power and torque: Akrapovič measured gains of 3.3 hp (2.4 kW) and 1.7 Nm at 11,550 rpm on a 2014 YZF-R25.
• Weight in that test: 3.1 kg versus 8.2 kg for the standard exhaust, a reduction of 62.2%. Figures may vary between motorcycles.
• Fitting: approximately 60 minutes.
• Noise insert: no dB killer is included.

This system is not road approved and does not meet emissions requirements for road or highway use. Installation triggers the engine warning light and requires ECU remapping; on Euro 5+ bikes with two lambda sensors, the warning results from a deviation in the original catalytic converter’s parameters.
