I bought a MS361 a little while ago. I rebuilt the carb, split the muffler and gutted the inside and then added a pipe to the side to make it a dual port. The compression is good at 165psi. I finally got to run it today in a lot of red oak and hickory with the 20" bar buried. Wow this is the most responsive saw to a muffler mod I've ever run. I ran it against my brothers stock 361 and it was a huge advantage with mine. He asked if I could do a dual port muffler mod for his 361 before next weekend as he loved mine. Sounds good to. Those mufflers are so choked up it's no wander it makes such a change.
