Whew!!! Big Kevin...[emoji16]

I think one outlet would be enough

The ported 90cc saws I do usually have 2 of these 1.5”openings and run extremely well, this ported 120cc saw has one, plus the factory opening is as big as its deflector will allow. I’m considering adding another opening ............

;)

Nice Mike...
Is there a point of diminished capacity with these muff mods? Where you go so big that you lose powah? Is there an optimal size that you look for?
Generally with mufflers I haven’t found a point of diminishing results but I do think that there is a point where all you begin to gain is noise. Ymmv
