Ok, before someone tells me to check the search and do my due-diligence, I will do that. LOL! My question is how much difference in performance should I expect if I port the muffler on an 044? I'm not a saw mechanic. I only run them... and run them well. LOL! How can increased performance be quantified? Can porting the muffler on my 044 give me noticeable difference? If so, how? Increase in horsepower? How much? 10%? 5%? Increased speed? Will the enhanced performance be that when I fire up my saw and start bucking wood, my first reaction will be "Woah!...this thing is rockin'!" ?? LOL! I did some reading on porting which only amounted to a few minutes, so that will be next, but it would be nice to see if someone ported their 044 and felt if it were worth it? Thanks, StihlRockin'
