Exhaust Stage6 Pro Replica MK2 for Yamaha Aerox / Jog / Minarelli engine

Description Exhaust Stage6 Pro Replica MK2 for Yamaha Aerox / Jog / Minarelli engine   Performance Pro Replica MK2 The completely reworked Stage6 Pro Replica MKII exhaust features some convincing improvements over its predecessor: torque sets in way earlier, followed by a significant power increase in the mid-range without losing torque in the upper rpm range. The result is a very easy to tune, powerful exhaust with a wide usable rpm range. Note: For homologation reasons, the Stage6 Pro Replica MK2 exhausts are equipped with two restrictors. One restrictor is welded into the manifold, the second one sits in the silencer. Keep in mind that the removing the restrictors revokes the homologation!

We achieved 10.74 hp with a torque of 8,51 Nm in combination with a 70 cc Stage6 Streetrace cast iron cylinder.

When installing a performance exhaust it is necessary to increase the jet size in the carburetor. Failure to do so may result in engine damage. Transmission and clutch tuning may also be required to get the best performance out of this exhaust.
