DIY $15 Silencer Muffler

[duke.55]

Just though some of you out there may be interested in this mod. Cheap silencer/muffler, works a treat and pretty cheap. Only a few gas/water fittings, old tin can and some steel wool. Let me know what you think?

I like DIY stuff. I've done something similar, separate in and out pipes with double walls two cans inside each other, no wool and wrapped with header tape to knock down the ping.

Once you quiet the exhaust you realize how much noise comes from the intake so next is an airbox for the intake like scooters have.

do you think this will fit on a sbp expansion chamber or should i just buy there silencer from them?

what does your engine sound like with that silencer?

Not sure about the SBP as I thought they were tuned and wouldnt want to mess to much with the flow?

The sound is heaps softer but you can still hear the slight 2 stroke zing...I love that sound, but Happy Valley is right, man there is some noise that comes from the intake & cooling fins that love to ring. I almost think I was targeting the wrong area for the most noise, even with the stock muffler internal drill and chop.

for the cooling fins you can place tire rubber in better them to help eliminate the vibrations and dampen the sounds of the piston. Card board and mouse pad can be used to help the clutch chatter.

wow, it looks like...... a tin can attached to a pipe...not much style there.

 

[HeadSmess]

mmmm, tin can on a stick...

wonder how long that 1/2" copper pipe will hold up before breaking... i see no brackets...

not bad for ameteur though would look good if it was steel and a decent size pipe.

intake noise can be a howler... working on it! the result of todays efforts seemed quieter... ride to work tomoza and see if its true...and not too "choked". pvc piiiipe

I still don't understand why so many people are obsessed with noise.
face it, 2 strokes are noisey for a reason and i think you should just let them sing how they were meant to.
true, a strightpipe with no muffler at all is too loud, but a modified stock muffler sounds great, is louder than stock and it goves more power.
I just don't understand the obsession with trying to quiet a 2 stroke down to a whisper.

I think it's just another part of the hobby. The quieter your mb is, the more places you can ride it without being encumbered by tickets or vengeful neighbors. Sometimes, it's not the volume of a sound but the type of sound that makes it pleasant or grating. I like these bikes, but a lot of people seem to hate the sound. I think there is something about the 2 stroke happytime sound that just brings out cager-rage like nothing else. And the dang dogs hear mine for a mile and wait to ambush!

Yeah, I agree, the quieter the better. I don't run any HT engines but do have some 2 strokes. My goal is to get them to the same noise level as as the small 4 strokes I have.
