If I were to choose because I also live here in Phils, I would be rather choose to install uma pipe,
Just to share I have a Sniper Classic loaded with 59mm JVT bore kit PnP Head, cams vspring and CDI using Sniper MXi 150 Uma Pipe, its not that noisy as open pipe but the performance is just like you are using a open pipe, I have Also MXi 150 And planning to install soon a Uma Pipe as per review with my colleges with who MXi 150 User the performance of uma Pipe was Supperb, and much cheaper on fuel consumption,
