Thread: 044 muffler mods again

Sorry fella's, I have searched this site for listings of 044 muffler mods again, and I could not find them. So, I am in need of you're assistance. I have two saws Walkerized, and have told my buddy of the gains, and he would like his muffler modified. I can do it, just need to know what I need to do to the inside of the muffler, and how big to make the two ports. The ports of my 372 are 7/8" o.d. Also, what needs to be done to jetting after muffler mods. Lastly, if anyone has a picture of their 044 or 046 muffler after mods, please post it. Thank you very much.

dual 7/8" is too big in my opinion. A pair of 5/8" should be plenty

maybe it helps a little...

He modyfied a 036, but the changes and the measurement are nearly equal imho....maybe a little bigger on the 044/046.
