This is the custom modded version for the Stihl ms361 or the farmertec g366... The insanely restrictive internal baffle has been removed(correctly )and an additional side port added... these do a great job of waking the ms361/g366 up....Exhaust Muffler For STHL MS341 MS361 Chainsaw 1135 140 0650
IMPORTANT... THERE ARE A FEW OTHER SUBSTANDARD VERSIONS OUT THERE. ONE DOESN'T EVEN HAVE THE INTERNAL BAFFLE REMOVED. THE SECOND THEY STICK A TORCH END IN THE BACK AND BURN OUT SOME OF THE INTERNAL BAFFLE. IT'S A HORRIBLE PROCESS LEAVING HALF THE INTERNAL BAFFLE IN PLACE BUT MELTED.. BUYER BEWARE.
