Muffler mod thread

I forgot, I've got another one that comes out the front.


660 clone

I have a couple of those on 066's, seem to be okay being gutted internally from the factory and that second "port" in the front cover- might have to try a third exit.

Here is a very placid and mild modification to my Jonsered 2159 muffler- hole is slightly larger on the actual muffler face and you can sandwich spark arrestor material between that and the front muffler support bracket- takes me to around 75% of the port size with this and the original outlet, but still legal in State Forests.

Real simple mod on a cat style 357/359 muffler. Split a pipe and make it long enough to add the opening to the jug side of the cat/baffle.

I like the looks of that one, the 288 one I did looks similar.

I like the way your Husky 5-series mufflers turn out. They look stockish but have a nice sound.

Thanks Greg. I've had a few guys ask me why I didn't mod the muffler. I told them to look closer.

Here is how I did the muffler on my ms361 clone. These are more of a bugger than most because you have to open up the can, gut it, and then braze or weld it all back together.

That's part of the art, in my opinion; Enhanced function without significantly altered form. Well, externally anyways.

Pretty much exactly how I do that saw Greg. Looks great.

I do a ton of muff mods. Easiest cheapest gain to be had plus keeps some heat out which is always a great thing. I try to make them look almost factory.. I try anyways lol .. strictly for demonstration purposes only.. haha

That’s what the first guy did. It was melting the muffler cover. Now the heat exits safely with out melting plastic

I did the same thing to mine. Did you leave some tube in the can as well?

Thats why there are bits missing and some carved out of my cover- so it is not there to melt.

no nice and flush inside. It’s a defector cover so he can choose is he wants to run the screen or not

Does the pipe stick out far enough to burn someone easily?
