Has anyone added aftermarket exhaust to a chainsaw?

You'd better make sure that isn't an EPA violation!

its probably more of a US Forest Service violation... spark arrestor...

I just got Chinese muffler of eBay with additional exhaust ports and have been happy with it for past 4+ years. Made it a little bit louder and felt like a little more torque, but it might be just be excited about new muffler.

An electric chainsaw doesn't need a muffler.

it needs a plastic bag over the idiot who bought it; minimum of at least brown paper sack so no one recognizes someone who bought one

A buddy just got a Milwaukee chainsaw. He uses it for limbing and pruning, works great for that, but he has a bunch of large Stihls and Husqvarnas for the real work.

The battery saws have their place, but if you want to actually cut a tree down and buck it up, it isn't meant for that.

I meant corded electric chainsaw. Not one of those light duty battery powered ones.

I have an E-go https://egopowerplus.com/commercial-top-handle-chainsaw-csx3000 and cut and buck coast live oak with it
sharp chain is always essential

I have three chainsaws. An old Stihl 025 from the 90's that has served me well and still runs great. I recently bought an Echo CS-271T top handle limbing saw that I keep in a sheath on my Kubota tractor. It is super handy and light and I love it. My third saw is a Stihl MS311 that I want to ask about.

I bought it about five years ago to help me deal with my wooded acreage here in Vermont. It's bigger and more powerful than my old 025 but still only has a 20" bar. I live on a dirt road that is not maintained by the local municpalities and my neighbors and I had to deal with a rather large downed tree in the road last winter. We eventually got it cut up but a 24" bar would have been really helpful.

So that gets me to my question. Chainsaws that come with 24" or longer bars are generally professional grade and I'm not willing to spend what it takes to buy one that I may or not need. I just bought an aftermarket muffler for my MS311 to help it handle a larger bar and I'm comfortable with the carb tuning but has any one else gone this route?

Be sure to run at least 40:1 of a CD rated 2 stroke oil.
I find just taking out the spark arrestor screen improves throttle response and changes air/exhaust flow enough to where a carb adjustment is usually needed.
I don't really mod my saws that much because I'm usually cutting kiln dried hard wood and stock power power is enough to smoke the bar and chain with the oiler turned all the way up.

Proper exhaust for a chainsaw. (Check out the babe at 5:12). I wouldn't want her chasing me with a rolling pin!

I've seen chainsaws with stinger pipes installed! These are for competition saws of course, so YES!
Think of 2 cycle motorcycle racing bikes if you don't know what I mean.
Looks like your solution will degrade performance significantly.

 

[billt460]

What if you just took out the screen and cleaned everything out real good? A lot of these spark arrestors can really clog up an engine.

I did the common "muffler mod" on my 346XP Husqvarna saw. It helped. But that was already a rip-snorting 50cc pro saw.

The idea that one can tune a small muffler's shape to optimize output is in error, simply low restriction will get you most of what is available. Nothing short of a proper expansion chamber works to make "big power". And, quite simply, this is not practical for the average saw user.

346’s are such great saws. Love my OE version. It’s tough to get the muffler modded properly on those due the awkward outlet position. I burned the top cover on one when I opened it up a bit too much.

Came here looking for how to make it quiet. I'm in the wrong place obviously.

Look at a Stihl forum. I'm sure a number of people can point you in the right direction.

Used this saw for some hurricane cleanup two days ago. It is a ripper, that's for sure. I'm using an Oregon chain that works like magic.

Depends on how restricted it was previously. A pipe will help, but only a little. Porting is the way to go.

I have never heard someone who was so much from Canada, and said "friends" as many times.
