    got bored today so i figured i would do an mm on this one,, now remember i did absolutely NO,,NONE,,0 cleaning on this saw,, this is the one i got last week,, anyway got the muffler off and decided on the right side, this muffler was easy to do,, no baffles or anything in the way,, i had the deflector so i fitted it to the muffler,, drilled a 1/2 inch hole the elongated it to 3/4 inch,,, added some screen then used 3 sheet metal screws to hold it all together,, here are the pics from start to finish,,,, it seemed to wake her a a bit,,don't know how much until i get her in some wood,, i did leave the factory exit port the way it was

    Nice job..o8..!!

    I much prefer a MM exit pointing forward rather than to the side..!!

    I have a 455 and will have to give that a try. Thanks for the pics. I just did this on a Poulan 3450.

    I do not blame you. I did this with a tig and blew a couple of holes in it and then had to go back and weld them up also. Practice Practice Practice.
