We used a Macs header for the OS 140RX and it fit nicely. It was only necessary to open up the bolt holes a little bit. If I remember right, the OS header would fit the Mintor, so it probably would work. As for the pipe, it depends. ES makes pipes that are a little different for gas engine applications. I think Ed Skorepa refers to it as a reversed flow pipe. I don't have all the details, but you could email him from his website and ask. A glow engine pipe will probably work, however if it's a CF pipe, keep in mind that the exhaust from a gas engine is hotter than a glow engine. THe ES pipes can take it, not sure about every other brand.
