bump! Anyone building this? I really need info. I'd like to use a pipe that fits on a vespa because the header that comes with this kit is just shit. Though i'd need exhaust mount machined. I don't even know what these guys were smokin when they made this shit. The header won't fit around the engine when the kit is mounted up. And as for now, I'm screwed on the exhaust. The output shaft needs to be 22mm and the bolts are 44mm center to center .. .any help ?
