any interest in silencer baffles?

[slugger]

I am looking at making silencer baffles (the part you wrap the packing material around) they would be 16 gage perforated steel and I can custom make them to your needs.
I currently have made 3. the size I made is 8" long and 1.25" diameter. the perforated hole diameter is .180
I have sent one to a board member here to test for fit finish and all that jazz. and I am looking forward to his input and feed back.

couple of things.

#1 what size is the most common?
or rather post and let me know what size your baffle is so I can get an idea of the different sizes I may be making.
#2 what would you be willing to pay for something like this. what would you say is a fair price.

thanks

chime in and let me know what you might need....please.....

I actually have a comment about this:

You should use a very thick but fine wire mesh instead of a tube with holes in it. The wire mesh opens more packing to the sound waves, so it's quieter and it's much deeper and "throatier" than the tube style. Just buy up sheets of this mesh stuff, cut it to size (length and width), roll it up into a tube, and weld a seam down it. Voila, you have a new baffle that is both quieter and better sounding. I have a very long post about hand-building mufflers that I will find momentarily and post up here if you want.

Here's the whole post I made:

The type of core you use, as well as the material you pack it with will also make a difference. I was actually thinking of home-making a couple cans myself, patterened after an SDG Racing exhaust I have. Basically all it is is a fine wire mesh core, packed with steel wool and then fiberglass, with a 1.5" inlet and 2" exhaust tip. The core is easily riveted in on two sides, or if you want you can weld some blind nuts to it and make it easily removable.

For a quiet, but throaty sound, you could make a "glasspack" silencer about 5 inches in diameter, maybe a foot and a half long. The inlet would be about an inch or an inch and a half, depending on the headpipe on your SX. Outlet could be the same size as the inlet for max power, or you could have a washer with a smaller inside diameter welded on the end for extra quieting. Maybe add a peice of 90 degree steel tubing for a turndown tip.

For a more "race-style" sound and performance, I'd do the same but with a foot-long silencer that was a little bit fatter in diameter.

And of course, you could always make "car-style" mufflers for it. Instead of a "core", these are pretty much just boxes or tubes with lots of barriers and walls in them, with holes cut in the walls/barriers to let the gas pass thru, but to slow the gas down and reduce sound. I think this is the style that the OEM's use for utility machines. This will not sound nearly as good as a well-made glasspack style muffler.

As for core design, you can use either mesh or a steel tube with holes in it. Keep in mind that Cobra uses the latter style, and their mufflers are always abhorrently loud. I would use mesh even if it takes longer or is harder to do, because it will open more of your packing to the sound waves in the exhaust, thus quieting the sound more completely.

And remember, you can always use novel shapes for your mufflers. Think of the Dubach Racing pipes, they're D-shaped to offer better tire clearance, but with a good amount of packing as well. The Mikado superbike silencers are diamond shaped, too. There's no limit to the shapes you can use. Make something and then show us!

I am a noobie so my experience is very limited. I thought the 16 gage would be strong enough to last for a long time and the circular perforations would help disperse some of the sound.
please find that thread so I can get up to speed on this.

the reason I thought about offering these was because we use this material at work and I can get the scrap cheap and the bending is not too difficult.

like I said earlier I sent one to a member here and he is going to test drive it for me and give me a report.

thanks for the input.

You honestly could go into the business of building performance mufflers at home, if you wanted to. Offer them in several popular sizes for universal applications, and maybe do measurements to custom fit other ones to specific machines. They're very simple to build, I have a little diagram on Photobucket that will explain it quite well.

If you can't weld worth a jack, have a friend or someone do it for 10 dollars an hour, it only takes about 2 minutes to do all the welding needed on a common muffler.

today I went to my engine builders shop, and checked out some goodies one of those goodies was a shearer inframe pipe and silencer, that silencer is made by shearer and its AWESOME! and after looking at it a while very easily done, its round so that the easy part!
