Hi,my spare brand new motor is all done now.I have quite a few mods on it.A 60mm BBK,head with bigger valves ,race cam,race clutch,no rev limit Cdi,30mm carb and a free flow exhaust.I would like to improve the exhaust flow a bit by using a bigger diameter header.My scoot is a Jonvay 150.Are bigger size headers available?.Thanks
