Quite Muffler

[OneTimeUser]

Tillotson 212; 24mm Nibbi, stock innards. I've got a garden variety exhaust with a hot dog muffler. Runs great but is NOISY. Scares the deer.

Any ideas for a quieter muffler that won't rob too much power?

Thanks in advance.

Are you using a genuine Briggs 294599 type or one of those Chinese copies? The Chinese copies screw-on but have no center seam and are more blingy. Never seen inside one of those. I wonder if that rainbow coating survives the heat…

I think someone here used two hot dogs welded together and doubled their fun. Be great if they came threaded on both ends.

The hot dog muffler quiets down the customary straight pipe header a good bit. Puts an end, largely, to the brappiness and if you didn’t re-jet, the backfire or I should say the poppety-pop-pop afterfire. The hot dog is a glorified spark arrestor… Even the box mufflers on riding mowers are loud.

You’re going to have to go bigger and more car like. A oval muffler with a chamber(s) and partitions?

Go to any parts store. Buy an 18 inch tail pipe evtension that will slide onto your muffler. get some hardware cloth. Roll a piece of that into abour a 1 inch tube the same length as the tail pipe piece. Wrap fiberglass insulation around the hardware cloth and slide in into the tail pipe. Drill a hole and use a screw to retain the baffle. It will be much quieter with no added restriction.

Go to any parts store. Buy an 18 inch tail pipe extension that will slide onto your muffler. get some hardware cloth. Roll a piece of that into abour a 1 inch tube the same length as the tail pipe piece. Wrap fiberglass insulation around the hardware cloth and slide in into the tail pipe. Drill a hole and use a screw to retain the baffle. It will be much quieter with no added restriction.

Thanks for this. I'm having a bit of trouble envisioning what you propose. Will you grace me with a picture please? I like the idea, but am drawing a blank on exactly what it is I'm looking for.

Many thanks in advance...

What is hardware cloth? I never heard of it.

Hardware cloth is quiet the material.

 

[Sparkwizard]

Galvanized wire fencing. It has 1/2 inch square holes in it. It is used for small animal enclosures, garden fencing.

Hardware cloth is quiet the material.

I see what you did.

So: a rolled single layer of hardware cloth mesh, a layer of fiberglass insulation wrapped around it, with the tailpipe extension over the whole shebang? I think the smallest diameter tail pipe is around 2” or so, and really, you don’t want to go smaller.

Got pictures of yours, Spark?

By the way OP, your taco bell farts scare the deer more than your hot dog muffler.

I think those screw in mufflers are 1.75 inch. Those tailpipes come in 1.5, 1.75, 1.875, 2, 2.25 , 2.5 and 3 inch diameter.
Get the one that fits your muffler. I do not have one at the moment, but there is nothing fancy about it.

Once the pipe is installed, the baffle can be removed and it will have an awesome rumble/ echo burbling sound. With the baffle installed, it has a much quieter almost puffing noise. Support the pipe. Don't just hang it on the muffler.
