    I have just successfully made a homemade quiet muffler. It was fairly easy. All you need is an empty Acetone can, 6 inches of galvenized pipe that will screw into exhaust port. First punch a hole on the bottom of the can, slightly smaller than the pipe. Second, attach it to the pipe. Make sure the cap is off!!!! screw the pipe into the exhaust port. To attach the can and pipe together you can solder, cold weld ,or braze. I used Liquid Steel cold weld, it will work great. Do not weld. Make sure cap is off!! Finally, crank the engine.

    I used it on my 11Hp briggs engine that was made in 1979!

    Just 2 questions (and I am NOT tring to be a smart alleck at all).
    1 how long will the can last???
    2 do you relize that the mufflers for this engine (minus the pipe) are only about 11 bucks for the round one and about 30 for the box one (retail).

    The can so far has done great. I do realize that the round mufflers are cheap
    but the box ones boy are they expensive almost 55 dollars. I can get a bunch of used rectangular mufflers for free. I just like to custom make things some times.

    The muffler for my Kohler 25 HP lists for 164.95. I've tried to weld it a few times to keep it in service. I was going to have a muffler shop weld me something that should be cheaper than the above. The mower is a Scotts 2554 built by JD.

    You can make the muffler perform even better by stuffing it with Stainless Steel pot scrubbers.
