If you google diy silencer you will find a very nice project that will rival the purchased ones. I'm all about diy'in with what's on hand. The first one i made cost me nothing but time. This one i purchased some chicken wire for 5.99$ and that was all i needed. This really does work to cut the decibels in half. I'm using insulation for the sound dampening materiel. If your exhausting in the house, then you will want to use polyfil batting for the queen size at a local arts and crafts shop. Comes in various sizes. The queen is enough for one 8 inch, or one 6 inch with some left over.


-Tools and supplies

Thx!! yes it is a no brainer... but your cost will be a bit more if you don't have buckets or insulation. An option for buckets is to go to a deli or restaurant ask for used food grade buckets. A cheap option for the sound batting would be to get an old quilt and take it apart maybe? just shooting some ideas at you...:Namaste::peace:

I've got the buckets and chicken wire, just gotta scrounge up some insulation.
Like you said, rip up and old quilt maybe, that's a good idea!
thanks again!

Nice muffler you made .. congratz. Just one question .. is it safe to have that fiber glass in direct contact with the exhaust air you are throwing into your own room ? .. i ask because im thinking of doing something simillar ... but not sure i would risk sending glass/wool particles in my room : /

This is an eight year old thread so not sure the op will answer. My self I think you have a good point so quilt batting would be a much safer bet.
