One of the real requirements here is spark arrestors, especially those who cut in the State Forest lands professionally. I never cared around my farm, but two of my "friends" I build saws for see that as a requirement Another for the ones in the more populated area's is noise. So one thing I see in a design like that box is an easy way to adjust the outlet for both additional mods and more importantly for here, spark arrestor screens. Hyway's muffler option on the AM saws I've done work really well for a whole variety of reasons. From looking professional to noise pressure. Good stuff. And they are cheap
