Hey yall, I have just acquired up my first 371xp I picked it with a scored piston and jug and naturally I am looking to do a little modding while I'm in there :msp_lol: I know this subject is well covered though despite my best efforts i have yet to satisfy my curiosity. I am looking to obtain information on the correct ratio for jug outlet size to muffler outlet size. I plan on building a new muffler out of stainless steel seeing as i have access to a tig welder to compliment my big bore kit. I am no stranger to chainsaws but at the same time i am no professional builder. Any help on design would be much appreciated.... by the way this site is freakin awesome!
