Poulan Muffler Diffusers

[Stihl-Pioneer]

I have been modifying the muffler on my Poulan 3450 a little at a time. I originally just drilled a hole in the original diffuser. Some of the older diffusers are NLA, but found the one from a PP365 type1 is still available for around $4. So I ordered a couple of them. It is exactly the same except it is a little longer so I just trimmed it off to the same length as the original. It is a little less work than drilling the original and looks original. She should breath a lot better consider the amount of holes in the 365 diffuser. This will work for a PP330,380 and Poulan 3750 also.

I take those and cut a V notch in the end that goes against the outside muffler cover. Lets the exh right out the end of it that way.
