Hi everyone, Does anyone know if there is a street legal exhaust system for the 2010 Cagiva Mito to give it more bite over the rev range? I live in Australia and I have been checking YouTube for ideas but I only see people in the UK and US with different systems, but I am not sure if they are legal here. I also read that changing the sprockets to ones with more or less teeth can directly effect performance. Is that true? Thanks for any advice.
