Has anyone tried altering the exhaust I am thinking of drilling the end to give it a better sound

  • I installed an exhaust made by Motofix in Cebu city. Sounds excellent and it would appear to have helped to increase km per liter.

  • did you notice any increase in power

  • Appears to have more power and better mileage . The spark plugs are not as black as on the first oil change so I think it was carberated a little rich before.

  • joel, where in cebu is motofix?
