I understand that, but it wasn't really my point. Let me put it a different way. If I wanted a top notch muffler job, but didn't have the tools, or the skill. Just seems that buying one already done would be the next logical step. Doesn't have to be that exact saw. From what I've seen, lots of saws have seen benefits from a muffler modification. I'm pretty happy with stock performance, and have zero experience with a muffler modification, so maybe it's a ridiculous idea. But it seems like a good way to generate extra income.
