Does the 575 use the same muffler? I have the left over parts from one I scrapped. I don't know that I ever had a muffler for it though. I'll look tonight, although bit very hopeful.

I have a 575 muffler it looks the same to me. Has a larger baffle the the 372.

Just my opinion guys, but I really appreciate Brad and Mike making this happen. I know I will rep both of them ASAP soon as i get a chance. I hope all will/can do the same. Same should also go for Andre and Nik as well. Thanks guys! This (to me anyways) is a big reason AS is a lot of fun!

I know I'll be hated for this, but would the AutoTune get "confused" if it adjust to the freer muffler only to be choked up later with the stocker?
C'mon man, we needs some Husky representation here dude. Besides, quite saws are for sissies.

Hi Andy and thanks for the pic of m-tronic muffler mod.
The 046 Isn't bad for an old school saw, it's no 7900 by a long shot, jab but not bad. Remember not every cut was made for simply the fastest time. All cuts were shown slow and fast, the only one not in the vid is the one where I cut out.
I'll let you all know as soon as the saw arrives, pics and video will fallow shortly after.
Mike I tried to return you call I got your VM, again feel free to call.
Someone asked for a MM pic.

Hi Andy and thanks for the pic of the m-tronic muffler mod.
I see now that it is a "full" spark-arrester muffler and that it has needed a "bit of surgery!". In the uk we just have a open round outlet - no spark arrester - about 18mm in dia. I total, it is now 23mm but more bias to the width than hight and after the usual stop/start and five consectutive cuts it is a different saw and getting stronger per tank. This particular saw runs a stihl ematic 25" bar and 3/8 RSC standard chain sawing 2year old fallen beech. We will see how things go as to mod the others as this is now "out of warrenty!. Thanks. Jon

Yeah well it seems like it has caught up with it pretty good the way it is. If someone wants to send a muffler to them be my guest.
I have both a 575 and 576 at the moment. The mufflers look the same to me. Really, they share almost all the same parts.
Damn PTO side of the 575 case is hogged out. Otherwise, I would have liked to run both back to back.
Kinda funny, but I'm jammed with 70cc saws at the moment. 046, 2 7900's, 3 372's, 2171, 575, and a 576. Love it.

The 575 I have here was absolutely destroyed, unlike any other newer saw I've ever seen. Even the stuffers on the crank were falling off. Were there issues with the 575 that have been since upgrade?

The early ones had crank issues which they later corrected. I had one of the early ones.

The baffle in the 575 angles down from the top has 4 holes that look about 3/8" in each corner. The numbers stamped on the side are different than the 576 but they look identical.

sux that the 441 has a crimped on front cover and is kinda a pita to mm compared to others. i'm modding mine this week and thinking about cutting a port out of the front on the bottom left corner at a 45 and welding it on.
If Brad has a muffler to use that's fine, but the 576 is on the heels of the 441 now anyway, so all I really need to do is find the time to run them a bit more.
Brad the fastest time the 361 cut was 23.47 with a chain that was getting pretty dull from cutting that Hickory.

Took a quick trip to Ohio and got to cut wood with the 441C. It acted just like it came out of the box new, sorting itself and a bit eratic. Where I go is 1050 ft. elevation. Savannah is at Sea Level. After 1/2 a minute and a couple of cuts she settled right down and went about business as usual. Smooth, strong, and predictable.
Upon returning to Savannah, Sea Level, I got to cut today and the same exact thing happened. It is really amazing to watch and feel the saw adjust itself to different elevations. Using the standard carb chainsaws I always have to take a bit of time to re-tune them for their environment. Not any more.
Seems like whenever I get to cut, which isn't enough because of where I live, or where I go the 441C is the choice. (Right now...) The only things that change are the bars from 20" to 28". People say the 60cc segment is a good one saw plan, well a good 70cc saw is a great one saw plan as well IMO.

That really is amazing John. I mean a chainsaw that can automatically change to suit its environs. Remarkable.

The technology on the 441cm is amazing. When you break it down, it is really that complicated. Does anyone have the shop manual or tech sheet for the 576 Auto Tune, like what Brad posted for the 441cm. I'm currious about how it operates and what functions it controls, thanks
Since the muffler is the same amongst the 570, 575, and 576 - they could definitely use a little opening up. It couldn't have been any larger than 1/2", 5/8" at the most in diameter, funnel shaped into the muffler.
Andre, I've got to address this comment. Not a 7900 by a long shot? I beg to differ with you. It's right on the heals of the 7900. It's a tried and true, proven runner. What's not to like? And don't give me this AV and filtration rhetoric. I ain't buyin' it. The vibes on Stihl saws have never been an issue to many, and the same with the filtration.
