Okay, here's the deal... I wanted to open up the muff while keeping the saw as quiet as possible. The way I did it was to open up as much area as I could outside of the baffle so the exhaust would still have to go through the baffle; it just wouldn't have to squeeze through the two absurdly tiny holes to get out. I did grind down the baffle a bit and bent in the recessed area so the exhaust has a straighter shot at the outlet, and I contoured (fancy word for "bent") the lip to make the opening sort of "3D" if you see what I mean. It is a pretty big opening. I also opened up the deflector a bit. My main concern is the baffle becoming the new restriction. I counted 22 1/4" holes in the baffle (11 per side) which ought to flow quite a bit, but I imagine my mod is still more restrictive than the "straight through the depression" mods I've seen most guys do since the exhaust must still go through the baffle. What do you guys think? Am I leaving a lot on the table by not "straight piping" through the depression or do you think the baffle will flow well enough? Any feedback/recommendations would be appreciated. I ran it and tuned the low speed, but haven't had a chance to tune the high speed yet (I finished late. My neighbors are good and I'd like to keep 'em that way...). It really didn't seem too much louder than stock, but it sounded WAY better and badder. Me likes! I'll have to get it tuned and do some cutting with it and see if it helped.
