Its cool to have you along. Are most guys tig welding the mufflers? Any worries about not running a screen?
If you have a TIG I'd say that's the best option, but most don't. If you know what you're doing MIG works, but I don't know what I'm doing so it doesn't work for me.[emoji51] Braising can work as well ,I've done it several times with good results. If you just want the gains and don't care about practically a hole in 5he front of the muffler works better than anything other than an expansion chamber.
Using a screen really just depends on the saws application and location you're using the saw. For myself I don't see a real need for a screen, it never gets that dry here, and if it does I'm not cutting anyway.

I was thinking of trying to tig weld it but with the mufflers being $40 + each I decided to try something different. Also the mufflers steel is only 0.30" thick and have never tig welded something that thin. So I tig welded the pipe to some 0.60" sheet metal and then I will mount that to the muffler.
Now I am not sure if I should drill small holes for sheet metal screws or use pop rivets?
This is my uncles saw that I am fixing up for his 60th birthday gift.

On this type of muffler it would be interesting to make a series of graduated spacers to place between the outer cover and the main body . You would also need longer screws and eventually you would start to intrude on the area of the teeth [ senior moment, can't think of what they are called]. It would be a lot more work than the tubular stingers but might be a new area of experimentation. Probably somebody has already tried it. Messing with reed spacers is common on motorcycle motors.

On my Poulan, I removed the baffle, drilled several 5/16 holes in it, top and bottom. Then, I removed the spark arrestor screen and reinstalled the baffle. On my pipe, it is bent around 30° and runs inside the muffler. It has a long angle cut and flared toward the exhaust port and the holes in the baffle. The pipe is about as long on the inside as it is on the outside.

I brazed the pipe in mine.

Closest I've come to exhaust mod. Believe it or not this beast runs really loud. I'm not much help, but what
would you expect of somebody does this to a saw

I reckon that is about as close as you can get to headers and straight pipes on a saw. I bet its loud....

Just finished up my uncles saw. Had some issues figuring out carb settings but I think I got it worked out. Chain isnt the best but it cuts.
Lean that thing out a bit. She's running way too rich.
Believe I would rotate that pipe some if I were running the saw. I run an old kart muffler on my old MAC. It will brand you if you are not careful.

That's cool. Never thought of that. If you don't , you should make the big bucks
