MOPED ARMY

custom. but since about 10 people on this whole forum do that. depends some pipes are for bottom end, some for top, and some are in the middle. it really depends when u want the power band to hit. really get it running. if your cylinder is messed up beyond repair there are 2 options, either get a stock one (cheaper and easier, slower) or get a kit (more expensive, harder, less reliable and faster). i would only kit if you plan on doing so down the road any way and have a good base of mechanical knowledge (like this is a circle clip ect.).
