I'm trying to figure out what to do with this muffler. There's not good place to put another deflector, other than the bottom. It fits nicely between the muffler and case and looks like a mouth, lol. The only possible issue is that it would blow straight forward in very close proximity to the bark. Shouldn't be an issue though once it's ported. It won't be in one place long enough to get that hot

Another option is to really open the muffler up at the factory opening. This would mean no longer having a functional spark arrestor. I'll probably end up selling this saw, so that may not be a good idea. Ideas?
