i was thinking again.... uh oh. if i got another spree mufler cut out all the baffles so i still had the expansion chamber i could throw it on the other sid of the spree.lol. i could fit a y valve to either direct the exhaust flow to the stock or modified muffler. how hard would it be to make a supercharger u think? it could basically be a re-enforced pump on a cam powered by the belt. i think i need to go to bed instead of these ideas.lol dont u hate it when people make these long * posts.
Right idea, but why not build/get a real expansion chamber and attach it to the end of the Spree pipe? Any 50cc expansion pipe can be made to work, or you can build your own.
