Decided to Make My Own Lawnmower Muffler

admin

I'm sure people on here will say that I have to figure in back pressure, spark arrestor, etc.  But i'm going to make one just for the hell of it.  I happened to have some stainless scrap, and just put it together in a way that was kinda different.  Instead of having a fiberglass or steel mesh packing, I decided to use baffles, kinda like a flowmaster muffler on a car, with a twist (literally).  Anyway, I still have to bend the pipes and drill some holes for the exhaust to get out and in.  First picture is one of the flanges I machined out of 1/4" stainless plate.Second picture is the parts I had laying around.Third picture is the flange welded to the "header" pipe.And the last one is part of the muffler internals.There are a few more baffles that aren't shown.I have no idea if this will sound good, or make/lose power.  But that's all part of the fun of trial and error without a flow bench.  It makes sense on paper so stay tuned...
