That looks very nice!

@Logger nate you should post a picture of yours for another option.

Well mine don’t look quite as good but is was easy and no welding required Mine has the SLR muffler, not quite as restrictive as a cat so left inside alone, for now...
I like outlets on the side better but wanted something that would direct more of the exhaust away from me when milling, this does the job.

The oil tank on that pretty saw will soon be all exhaust stained...

Another 6401 I did.

It acts as an oil warmer in the winter months .
I think its better than having it on the "drivers side" as I've seen many and had one. Its good to see what others are doing, even if it isn't how we would do it it helps us to think about things more, and for those who were looking for a similar solution there it is.

Next time make the deflector elliptical and the muffler will have a smiley face.

Could end up with exhaust stain on front, hasn’t so far. The way the deflector is angled it actually keeps it away from the front of the saw pretty good. Might not look as good but so far in function I like it better than drivers side or straight out the front.
Bottom of muffler just needs to be more round for smiley face , lol.

Here is the one I did on my 6401. I painted it with high temp paint afterwards but forgot to take a pic of it painted before I put it back on the saw.i also heated the crimp and split it open to cut that baffle out.

The pic of my 6421 had the muff modded before it ever had fuel in it.

Just in case you forgot what it looked like.

5 tanks so far...
Seems to work real well so far. Sure seems to help keep exhaust away when milling. I’ve used 044, 064, 661, 372, 385, 576 for milling this is probably my favorite set up so far. A 572 with similar kind of outlet would probably work real well too (on my wish list). The 385 had an outlet that blew the exhaust right into the square tube on the mill, got so hot couldn’t hold your hand on it, sounded good though.

Five tanks, that saw is still new, get back to us when it has a hundred or so, my oldest 044 passed 1000 tanks four years ago.

So 100 tanks is soon .

 

[pioneerguy600]

While 7 - 8 tanks a day is normal for me and getting to 100 doesn`t take long, seems soon is just a matter of weeks for a saw actually being used but may be a long time for shelf queens.....LOL

Yep, many of us are weekend warriors or that plus a little during the week. Then when you have a bunch of saws it's hard for them to get more than a few tanks each per month. I have to go out and cut cookies just to keep some fuel circulating through mine.
Sounds like your running more thru yours than many on here are.

There are times, though less now than years gone by. Age plus machinery is taking its toll but I still get some good days in.

I don't have that much wood available to me to cut unless I'm cutting for free. I have more than enough firewood on the split pile then theres lots of rounds, then when those are gone I've got a pile of logs. If I'm running 7-8 tanks thru a few different saws in a day, that's a nice payday or a buddy is getting a heck of a favor.

 

[pioneerguy600]

We clear building lots, get paid plus keep the wood if we want it. Have more lots to be done than we can handle.

 

[pioneerguy600]

Years back clearing 1,500 - 2,000 acre blocks was common, cutting power transmission lines 60' wide by sections up to 20 miles long through mature hard and softwood. Put a lot of hours on chainsaws.
