actually having good luck with this muffler idea

[guff]

on the non oem spark arrestor side of my 440 and 066 dual port mufflers...i wanted to put screens in..so i got my screens and steel pop rivets and washers ....peined the rivet over the washer in the mufflers carefully...been a year and no problems...quick cheap solution..and i don't see any failure in the future...everything looks good............................i'd like to see some pics of a muffler mod on a husky 55 however if anyones done it..or to know atleast how far to open her up......thanks.....guff
