Just a though here guys.
At work they thru out a bunch of small fire extinguishers. Some metal and some aluminum. about 4" diameter.
I salvage just for something like this.
The aluminum would sure keep them light.

With the heavy vibes of these small engines, I'm not sure if aluminum would stand up over the long haul. Might do fine though. Weight isn't really an issue with the K series, as there are good spots to bolt braces on. This one is bolted solid with a heavy brace & is solid as can be. As to just simple weight, we're always looking for ways to add weight anyway. Long as braced properly, extra weighty mufflers won't hurt anything.

I have a friend who does stainless exhaust systems for cars and trucks. He stocks pipe in sizes from 1" through 4" with many sizes in between. If I can scare up some flat stock for the baffles and flanges, I intend to build one for all of my Wheel Horses. All the ones that I have, have the Nelson mufflers on them and they are expensive to replace! My latest acquisition, the 312's muffler is shot, so I'm gonna start with that one and see how it turns out.

Stainless is the way to go for exhaust.

Great muffler you built there! One of these days I'm going to try to build one, but my skills on welding thin metal are, shall we say, inadequate at best.

Well, Chuck, who bought the tractor from me had to go over one of the welds I didn't get right.
