Honestly. ...I got 2 options for u.....buy my 350 grab bag here on the trading post for $60....or buy new am from hlsupply on ebay for $30 or so...sometimes ebay has some good deals on mufflers
Friday bump.... had this saw up against one of my 455's... its at least as fast. at least. Had the 18" bar buried in maple ... at 9:30pm the other night... 22degF .... saw was great. ....comp now 175!
