If it works for you- it works for you.
Over here for what I do and species I cut- very real chance of setting the bark of most species smoldering.
Left unnoticed, very real chance of setting woodlot/forest on fire.
Its an issue when full bar cutting big logs and the muffler is near brushing the bark- worse with a dull chain and saw being forced.
I just run the stock Stihl dual port mufflers on these and 046/460 models- understand that might not be an easy option in the States- but there aftermarket dual port fronts available.
