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.
