It's a full rebuild... Haven't had a chance to run it yet. Started it up after the first muffler mod -- needed to open the low end a bit to get it to idle. Just got the bar today so hopefully I can get some time this weekend try it out. I did a little grinding on the cylinder (this saw was a pure cad purchase). I hope to embarrass my buddies stock 357xp.

Hey, no hard feelings with that song last week 
I know I won't be the next American idol, but ya gotta say it was pretty darn funny.
I want to mod my Sthil.
I really like the way that looks.
I can borrow a small mig welder.

Careful with that MIG Mike. They can leave spatter partially stuck inside the muffler (if you weld it on the inside) that could come loose later and wind up inside the cylinder. Braze or TIG is preferred here.Hey, no hard feelings with that song last week

What stihl do you have? A lot of them can be opened without the need for welding or deflectors.

I think the 311 is pretty much like the 361 muffler. You can weld a pipe or use a husky screw on deflector.

Definitely worth doing

Was the pipe you brazed onto the muffler stainless steel or aluminum conduit? The first post said aluminum, I was wondering how you got that to stick to steel with brass brazing rod......
Welding stainless steel to steel isn't complicated at all, with a mig or tig, IMO. I've done it a lot over the years.
I'll be doing some "dual exhaust" soon on the 051, the 372XP, and the MS046 (which is also gettin' a big bore kit this winter).
Nice job Mike!

The first pipe was a piece of electrical emt conduit... I was thinking it was aluminum (I even had it in my aluminum scrap pile) must not be since the bronze stuck to it. Shows what I know about brazing and gas welding 
I had an a hour this afternoon to play with the saw. Spent the first 45 minutes trying to tune the saw. I would think I had it but I just couldn't get it to idle right. It would run fine and accelerate great and then all of I sudden it would die if I let the saw idle for more than 10 seconds or so. I swapped out the carb with another one and the saw started on the third pull, idles well and sounds great.
It has a brand new piston and rings but it is already noticeably stronger the my ms361. Pulls a 20" 3/8" chain like a saw should. I was trying to take it easy while it breaks in, but you can really lean on it with chain buried.
