Chainsaw Repair

Got my hyway muffler today looks great. Do you guys think it needs another exit hole and a deflector or cut it in half and remove the innards? Also got my first meteor piston today and they are very nice looking as well. Should have the rest of the parts tomorrow to start putting it back together. Have the new crank bearings in already and the rest of the parts are washed. Carb is rebuilt and ready to go. Does anyone have any pics they would like to see while I am putting it back together for reference or knowledge?
