Let's Start a Muff Mod Thread

[SS Sniper]

Homelite410 does some nice work.

I have one that is pretty off the wall.

No fear, I can put it back to the stock louvers in a wag of a lambs tail!

Blast from the past. I like Andy's (Lakeside53) solution to doing an MM and still having an effective unrestricted spark arrestor. Unfortunately most of the pics are gone. http://www.arboristsite.com/community/threads/lakeside53s-361-muffler-mod-w-photos.33528/

I always use a screen when doing an mm.

562 mod with screen intact

I think Andy said that a flat screen over a hole restricts it pretty good with just a little carbon buildup and his method with the screen tube inside had a lot more area to help with that. I don't run screens on mine.

 

[SquareFile]

The screen I use was recommended by Mastermind. 67% open. Stainless steel mesh from amazon. I don't think carbon would build up. I like using screens to prevent objects getting in.

Helpful video for MS290, 310, 390 family



Louder isn't necessarily better or more powerful. Baffles are sometimes designed to improve flow @ specific RPM. Think cars with "tuned exhaust", "tuned intake" and the geometry of car engine header tubes. These are all built like musical instruments to RESONATE at a specific frequency(RPM). If you can do this to your saw, BAM, power band. If you want it to "look cool" just go ahead and hang some "danglies" (bar fastening devices) off the rear handle and make it match the hitch on your truck.

Here's a couple examples dealing with cars but the same techniques and theories apply





Hope this was helpful

thankyou for posting you work , I found it very helpful, you didn't say what fuel oil mix you run and what ratio, I use a Castrol synthetic and a 98 octain unleaded fuel at 25 to 1

Just had to put this one up. LOL Haven't started the saw yet to hear it ? A good friend gave the cover to me to put on my 064 , just put it on the other day .View attachment 337865

that's Gnarly. I like how the front bead sight was left on. Guns and chain saws two great things

 

[LegDeLimber]

Do the double barrel scatter guns come with swappable chokes?
Could be a new tuning aid here.

Oh yes, hearing protection is a must.
However I feell that it was worth it.

. This is my 2188. Pipe goes thru to other side of muff, with long pipe and little ports inside of pipe it pulls some exhaust back into muff for some back pressure but still let's it breath ,1in pipe. Quiets a little too.

371xp with copper elbows brazed in. Sounds nice

 

[Ronaldo]

Jonsered 2152 with piece of electrical conduit brazed in. Nice low throaty tone.

YUP!

those of us NOT in the trade don't need to worry about noise.

This one will wake the dead. It was my first chainsaw mod after coming to these pages.

The 361 was THE saw to cure every diabolical illness known to man.

Rumor was the 359 was just as stout if'n it could breath?


Let's just say I let her breath!

I can't take credit for this one. But it's a clean 2nd port
