It looks really good! Too bad it didn't make much of a difference. Those briggs motors are just simply loud. I know folks that have tried to quiet them down with little luck. You get an A for effort though!
I have a 6500/7500 PowerMate genny in a Suncast dual trash can shed. I've been considering altering the muffler to quiet it down, but as noted, these rigs are LOUD, period. Many YT videos confirm this...thank you for sharing your test! It's not so much the exhaust. Some guy has a video up that quiets a genny 10x in 10 seconds.....he lays plywood sheets all around the genny. Insulation/sound deadening seems to be the key. I'm guessing my next move is a sound insulation attempt. The way my Powermate is set up, the exhaust is on the 'left side' along with recoil pull handle. Power panel on the 'right'. The exhaust points out one of the two shed doors, the other I can close along with the roof of the shed. The exhaust door will always have to be open during operation, which is ok with me. Hopefully, with sound deadening material applied to all interior surfaces the engine noise will drop some.
Studio DaVeed The exhausts on those Tecumseh engines aren't quiet at all. A better exhaust would definitely help, but air cooled engines aren't that quiet to begin with. The engines would be much quieter if it was suspended in some springs and rubber pads to absorb the vibrations. I am planning on building a generator that will run at a lower 1800 rpm instead of screaming at 3600 rpm using an 18 HP Onan engine. The lower rpm will be far less noisy. I will be using small springs with rubber pads for the engine mounts to keep the noise down. I am using the stick mufflers but I'm welding pipes to redirect the exhaust into another resignation chamber to make the exhaust sound like a steady "hmmm". Lastly, the entire setup will be put into a wooden box with sound dampening material on the inside. The exhaust will exit out the side of the box with thermal insulation to protect the wood. I have a 10kW generator head rated at 3600 rpm that is shaft driven so I will have to use 3 individual v-belt pulleys at a 2:1 ratio.
Lean a piece of plywood against it with the plywood facing you, makes a huge difference in the noise that makes it to you. Trick we did when I was framing houses.
Do not forget about generator safety ua-cam.com/video/I1jT3ANENvI/v-deo.html keep in mind that portable generators can be dangerous if not used carefully. Especially it’s important to keep children safe when you’re using portable generators. Thank you. Stay safe
Honesty is lacking is most reviews. You are completely honest and objective and I for one respect that. Thank you for the information. I have a large Winco Generator with a Honda engine. It’s as quiet as it can be but as you said, the actual engine noise is louder than the muffler.
I always said that to myself.Wood framing with foam insultions on the inside.Plus keeping it cool because of the restriction once covering it up.You must be in to construction or the Engineers in the service.It's not the most genius idea,but you have to knowledge in at least three different fields.Framing,sound deadening,and cooling.Excellent input and idea.
I've been wondering this my whole thinking life ... how a 70's Cadillac with a huge 200hp v8 can be nearly silent at idle, but a cycle or small engine always has to be annoyingly loud - good on you for trying this and putting it together
Air-cooled vs watercooled motor, air-cooled engines have very thin metal around the cylinder vs a watercooles car engine, that reduces alot of the combustion noise, I'm sure the water running through the block helps reduce it to. Also, having a 12-foot-long exhaust pipe helps too, having the engine enclosed under the hood helps too.
You are not hearing the sound of the exhaust you are hearing the sound of the engine. It is not a very well balanced engine. Lots of vibrations lots of noise.
There are two things to consider when trying to quiet down a small engine. #1 The amount of metal and thickness of the crank case and cylinder and cylinder head. Small, air cooled, engines have very little metal in the engine housing itself so a lot of the combustion noise is actually coming through the walls of the engine. This can be addresses by enclosing the engine in a sound dampening housing. however this is problematic with air cooled engines. #2 No matter how quiet a muffler claims to be, it is greatly influenced by the length of exhaust tubing. The longer the exhaust tubing the quieter the the sound. The exhaust noise is greatly reduced by the distance and turns and surfaces in which the exhaust, and pressure wave, has to transverse.

Thanks for doing this, I have been contemplating doing the same thing! You saved me the exact amount of time and money you spent on this experiment. Thanks again, I really appreciate it.
A company I worked for a long time ago actually bought a device to pick up the sounds in an exhaust, delay it, and play it back thru a speaker in the exhaust 180 out of phase to cancel the noise. Not my project, so don't know how well it worked, but based on this video I suspect there was a reason it was just sitting on a shelf in the conference room.
Thanks Edwin. I enjoy trying to make things work better for us . I didn’t want a box because we move it all around the farm when the power goes out to run water wells for the cows. I still want to try a few more things on it. Have a good weekend.
I don't have very much experience with generators. However, as a semi-retired auto mechanic. I know that muffling the INTAKE of an air compressor does wonders for quieting them down inside the shop. In fact, the only difference I've noticed on standard vs. ultra quiet compressors is the intake has been muffled on the ultra quiet ones. Might be something to try out on a future video. Also, you wouldn't have to worry as much about heat and that would free you up to use a wider variety of materials. Just some thoughts. I just found your channel and have subbed.
I had a single stage air compressor for airbrushing. I put in a sealed container with sound deadening material on the inside. It worked perfectly but the only issue was heat being stuck inside the enclosure. The compressor was way hot after an hour of use. I'm sure there is a way to do this without any bad side effects.....
I tried the same thing about 10 or 12 years ago. It was during that terrible terrible ice storm we were hit by. The stores all throughout the Midwest and Northeast of the United States. Had no generators left, including being sold out of every gas powered heater they could get their hands on. It was all a terrible experience I'll never forget. How are utilities work turned back on for a total of 16 - 24hr. days & 9hrs. I'll never forget it. I had a brand new portable ®Mr. Heat buddy heater, along with my heater I had two generators running non-stop for almost 3 whole weeks..!! Needless to say but that ice storm was the worst to hit America in over 20 years. I must also say.. that ice storm taught me how to install and retrofit a used car muffler on to my generator. The first one(muffler) worked great with a HUGE reduction in the exhaust noises. Thank God !! I just wanted to share that itty bitty bit of interesting information on your topic. Thanks
Most of the noise from those type of small engines comes from the engine itself since nearly all of them run at 3600rpm. I think an absorption muffler like a glasspack would be quieter. Most of those car mufflers have passages and chambers that are too big for a small engine to slow the exhaust flow and direct it to quiet it down enough.
It would take 8 years 7 months and 6 days to heat up a cup of coffee just by yelling at it. Sound wouldn't be to efficient producing energy. I'm pretty sure if you harnessed every sound a generator makes in the whole US you might have something decent.
You are a man of heart and soul. A valiant effort! Better luck on the next one. I might suggest an old motorcycle muffler that has a baffled inside. You can find them in old salvage motorcycle parts shops. They work very well for bike exhaust. The baffle does all the work. Give that a try. Mike in Colorado
Thanks for doing an honest test on this subject and sharing with folks. You may have saved a lot of guys some money with your demo. One fundamental issue with small air cooled engines is they have much less mass and no water jacket to help control all that nasty sound. The noise just doesn't get absorbed. Better to build a small sound absorbing shed to place the generator in. Then use the auto muffler to safely exhaust the fumes and heat from the building.
I'd suspect a motorbike muffler would be better matched to this size engine, they also put rubber bungs in between the fins to deaden mechanical ringing noise on air cooled motorbikes.
miggs225 there are so many factors to consider. In car, sound gets absorbed in a long exhaust pipe. The longer the sound travels in an enclosed pipe the more it looses the energy and finaly calms down by the time it passes through the muffler which reduces it further to almost quite. The exhaust pipe is purposely hang on rubbers which also helps to absorb the vibration from the moving gas that comes out with a pounding force. Secondly, most genders are two strokes engine.the interval between the firing in the cylinders is very long. If a genset is made with 6 cylinders, it will produce less sound bkoz the firing will happen at close intervals hence sound will come out smooth like bruuuuuuuuu than braaarrrrrrr Thirdly, the sound doesn't just come from the exhaust pipe alone but also comes out directly from the thin cylinder walls. The only way to contain the sound is to cover with a sound proof box.
The resonator in an exhaust is tuned to a specific engine speed to reduce volume at that frequency of exhaust pulses. Car exhausts usually have a variable resonator that opens up at high speed (pressure activated) that offers a second tuning for the higher frequency. The small engine is probably running at a lower RPM than the resonator is tuned for. I'd try using a scooter exhaust. I doubt if a motorcycle exhaust would have much effect, either, since they're usually tuned for higher RPM ranges.
That's a good thought but, the engine is connected to the generator at a 1-1 ratio. So the engine is set to run at 3600 rpm (which is around or above the resonate frequency of most mufflers) to provide the 60 HZ electrical output. My theory is that the 3/4" pipe connecting the muffler to the engine is too small, therefore keeping velocity too high. I think had he used the short run before the turn to put a larger diameter pipe (like 1-1/4 or 1-1/2) then reduced back to 3/4, would lower velocity and allow the pressure waves to react against one another. A lot of automobiles have this very thing (a resonator) usually behind or built into the Cat.
Thanks for an honest opinion. My same conclusion. Most people would say it was quieter if it was their video. This experiment tells me to look for another option. Thank you for a great video with honest results.
Make your own muffler, just larger, use a 55 gallon drum lined with something. Might sound deeper. Most sound probably come from engine not exhaust. Put it in a doghouse or shed with exhaust outside shed.
Thank you for showing that it didn't make any difference. I always wondered if it would make it quite you showed many many people that it doesn't make a difference if a car muffler is connected.
That's interesting findings. I retrofitted the stock muffler from my Triumph Speed Triple motorcycle to work on a Generac generator with the same engine and it's much quiter than the factory muffler. Perhaps the automotive muffler is too high flow for effective sound deadening on this application.
@@100pyatt put a little re-bond carpet padding or horsehair carpet pad onto the plywood and that should make a very good noise insulator, just keep enough distance between the padding and anything hot. Leave the top open and raise the bottom just enough to get air circulation. You can get clean used carpet pad free from most any carpet shop as its recycled and they probably wouldn't mind if you pulled some from their recycle bin as long as you didn't leave a mess
Hey pal. Stopped in to support and say hello. I met you in one of the streams I follow for sure. When I first saw you putting that on I was like "WOW THATS A GREAT IDEA!!!!"... Part of me was a little bummed when it wasnt quieter. Very cool to try it though. Loved watching it. I was excited to see if it worked. hahaha Thanks for sharing.
Can assure you it works very well but learned the hard way about over insulating exhaust because had a huge build up of carbon in the cylinder & started running rough after long hours of operation ended up having to pull head off & clean piston & valves but other than that its the way to go.
The vast majority of sound on a conventional generator is from the engine internals and the actual genset on them. That’s one of the reasons inverter generators are so quiet.
Yes, the intake makes noise. Use this muffler for the intake. For exhaust, as soon as you can, increase the pipe to 1.5, then flex pipe to a glass pack muffler mounted with rubber hangers. Or just put a plywood cage around the generator (walls angled in just a bit)
A few things I did was add muffler(with equal results) , added a small set of valve springs inside the factory springs (coil over springs like older V8's had), and took valves from a 1.6L kia rio and crudely cut the length of the stems to be slightly longer than the factory valves. That way the valve train noise was almost eliminated . Aluminum transmits harmonics exceptionally well, which is a big problem when seeking to reduce the overall noise these engines produce. If you look at newer F150 trucks, on the exhaust system they have a exhaust clamp with a bar about 6 inches long with a large weight attached to the end of it. I took notice of this and attached a bracket to the engine, drilled and threaded 2 holes, one in front of the other separated by 2 inches or so. Used a long 'all thread' (1/2 inch) , attached a bunch of large heavy washers to the end, and started up the engine. Slowly turned the rod increasing the distance of the weight from the engine. It began to vibrate violently but kept going till it stopped and the noise was almost eliminated. The harmonic frequency was matched , canceling itself out. This alone ,without adding valves,springs, and muffler is by far the best thing you can do to quite down these things. Give it a shot, its cheap and easy , try a 3/8 all thread, it might work better .
Thanks for watching. We’re going to do more experiments on it soon as I get time. Things are crazy on the farm. The all thread sounds like a good idea. We might try some of your value tricks also. Thanks for the info. Have a good week
The most important thing is vibration control. Right off the exhaust port I used a Stainless Steel exhaust flex pipe (with SS braid on the outside) to isolate the engine from the solidly mounted exhaust as any weak point between the two will fail quickly, as in the aluminum engines exhaust port/mount breaking apart.
T.T. - wrong because of what? The muffler he used is a baffled chamber. A flow through muffler uses a different technology that absorbs sounds without baffles. Is that what you’re suggesting? I saw that explanation on another video but not sure if I understand it completely. I have a chipper shredder that mostly runs wide open when it’s working and it seems much louder than the previous Craftsman chipper shredders I’ve had.
I am always amazed that so many people believe the problem with excessive generator noise is from the discharge of exhaust. While improving exhaust muffler application will have some minor impact. The vast amount of noise is being produced by the MECHANICAL ACTION INSIDE THE ENGINE. The MOVEMENT and ACTIONS of the Valves, springs Rod(s) Crankshaft and Piston(s) DEVELOP the MAJORITY of the NOISES HEARD The Engine case acts like a “bell” in amplifying and distributing these sounds OUTWARD FROM THE ENGINE AT GREAT VOLUME. A better approach would be to construct or apply an insulated cover for the WHOLE UNIT with allowances made for operating temperature and exhaust gases. But just throwing a muffler on it, is not the answer.
Damn, it's too bad that didn't work out. But I appreciate the work you put in. I just got a generator, and I'd like to quiet it down, and I had the same idea of using a car muffler. I guess I won't bother now. Thanks for your work, and putting it up on UA-cam.
We Bury our gen in a 6 by 6 hole with lid that has plenty ventilation and a fan. Also the hole is lined with polyethylene Foam board and lid as well. When closed we can barely hear it. 👍
Long ago a neighbour put open headers on a mud truck. They came out of the bonnet through holes he made. It was painful loud. I told him perhaps cutting down the pipes and putting glass packs on the open headers may help. I could not believe the difference! It was still loud but not painful nor too harsh. The red glass packs looked great with flap valves on the end.
The noise from the Briggs engines comes through the case. I took carpet and stapled it to plywood and placed it on the 4 sides and top and bottom leaving the the top and side that faced away from the house with openings for venting. It was a big improvement.
@@GerraldFarms, I've always wondered about this and glad to see someone try it. The other problem with the Briggs is oil consumption. I gave up on my Briggs and went to a Harbor Freight. The electrical wave is "noisy". Electric motors run by it sound different and buzz. The engine itself is much much quieter though and fuel efficient. Bottom line if you want a quiet, long lasting, good signal generator pay the big bucks but that make life less of a challenge and less fun :-)
I've got a 40 yo B&S generator and it still runs great. Loud as hell. On this project, it seems like a whole lot of places to get really hot and burn. Fun video. You never know unless you try!!!
While using these gen sets in the Army we just dug a deep hole, tossed in a wooden pallet and then placed the the generator on it, the earth is a great sound absorbent. While you are at it fab a tarp to keep the rain off. Cheep & quite.
Clay Ritchie thanks for watching. That would work. I still want to try a few more things on it soon as I get time. Things are crazy on the farm right now. Have a good one
Great video , the problem with these engine is that it's made of a thin metal with no water so alot of noise is coming from the head and the block . You can easily quite a generator by building an enclouser with foam pads inside and an electric fan . Which will make a BIG difference
Stopping the video @ 0:01 seconds to comment. Yes, a car muffler will help HUGELY! I did one on my 5HP B&S 20 gallon air compressor and it helped, but those air cooled engines are still LOUD as hell and putting the whole thing in an enclosure will also help HUGELY. I recently rebuilt a 3 HP 1700 watt generator, a 1979 3W091A Dayton/Onan generator and installed my Air compressor exhaust using a few lengths of black gas pipe for connecting the two and it's not bad at all.
Thanks for watching.I plan to do more test on it. Soon as i get time on the farm.I like to try and make stuff work instead of just buying another.Have a good weekend.

Put a pair of noise canceling headphones around the muffler it will make it sound like a electric motor👍
A company I worked for a long time ago actually bought a device to pick up the sounds in an exhaust, delay it, and play it back thru a speaker in the exhaust 180 out of phase to cancel the noise. Not my project, so don't know how well it worked, but based on this video I suspect there was a reason it was just sitting on a shelf in the conference room.

You are an honest man! Build an insulated box with good venting! Will solve that problem! Great video!
Thanks Edwin. I enjoy trying to make things work better for us . I didn’t want a box because we move it all around the farm when the power goes out to run water wells for the cows. I still want to try a few more things on it. Have a good weekend.
Glad this was in my recommended. Definitely a nice effort. I recently bought a generator, and wondered if it could be made a little more quiet.
Lord Motorsports thanks for watching. We’re going to do more experiments on it. Have a good weekend
I don't have very much experience with generators. However, as a semi-retired auto mechanic. I know that muffling the INTAKE of an air compressor does wonders for quieting them down inside the shop. In fact, the only difference I've noticed on standard vs. ultra quiet compressors is the intake has been muffled on the ultra quiet ones. Might be something to try out on a future video. Also, you wouldn't have to worry as much about heat and that would free you up to use a wider variety of materials. Just some thoughts. I just found your channel and have subbed.
This could have easily been a :30 second video. A key to having a popular YT channel is knowing when and where to EDIT!
Bummer dude! I was hoping it would make it quieter as well. Only option left is a soundproof enclosure.
Bennet Fox thanks for watching. We’re going to do more experiments on it. Have a good one
I had a single stage air compressor for airbrushing. I put in a sealed container with sound deadening material on the inside. It worked perfectly but the only issue was heat being stuck inside the enclosure. The compressor was way hot after an hour of use. I'm sure there is a way to do this without any bad side effects.....
I tried the same thing about 10 or 12 years ago. It was during that terrible terrible ice storm we were hit by. The stores all throughout the Midwest and Northeast of the United States. Had no generators left, including being sold out of every gas powered heater they could get their hands on. It was all a terrible experience I'll never forget. How are utilities work turned back on for a total of 16 - 24hr. days & 9hrs. I'll never forget it. I had a brand new portable ®Mr. Heat buddy heater, along with my heater I had two generators running non-stop for almost 3 whole weeks..!! Needless to say but that ice storm was the worst to hit America in over 20 years. I must also say.. that ice storm taught me how to install and retrofit a used car muffler on to my generator. The first one(muffler) worked great with a HUGE reduction in the exhaust noises. Thank God !! I just wanted to share that itty bitty bit of interesting information on your topic. Thanks
5star King thanks for watching. We’re going to do more experiments on it. Have a good weekend
Most of the noise from those type of small engines comes from the engine itself since nearly all of them run at 3600rpm. I think an absorption muffler like a glasspack would be quieter. Most of those car mufflers have passages and chambers that are too big for a small engine to slow the exhaust flow and direct it to quiet it down enough.
I agree . Thanks for watching and commenting. Have a good one
Like the saying goes,
"It takes a man to admit it"
and boy , you're the man.
Good informative video though.. thanks.
I think scientists should start investigating converting sound energy into something useful, so that sound is not just wasted like that.
Naziru Adam thanks for watching. Have a good one
It would take 8 years 7 months and 6 days to heat up a cup of coffee just by yelling at it. Sound wouldn't be to efficient producing energy. I'm pretty sure if you harnessed every sound a generator makes in the whole US you might have something decent.
@@conker33350 you obviously don't know my ex wife. She could break glass
@@Bryan-Hensley you win. That shit was funny
Yeah I got some Trump OG oil .
I was hoping it would work man definitely A for ingenuity and effort.
You are a man of heart and soul. A valiant effort! Better luck on the next one. I might suggest an old motorcycle muffler that has a baffled inside. You can find them in old salvage motorcycle parts shops. They work very well for bike exhaust. The baffle does all the work. Give that a try. Mike in Colorado
Mike Schroder thanks for watching. More experiments to come. Have a good one
Thanks for doing an honest test on this subject and sharing with folks. You may have saved a lot of guys some money with your demo. One fundamental issue with small air cooled engines is they have much less mass and no water jacket to help control all that nasty sound. The noise just doesn't get absorbed. Better to build a small sound absorbing shed to place the generator in. Then use the auto muffler to safely exhaust the fumes and heat from the building.
Thanks for watching. I enjoy trying to make something work. I’m still going to try a few more experiments on it. Soon as I get time. Have a good one
I'd suspect a motorbike muffler would be better matched to this size engine, they also put rubber bungs in between the fins to deaden mechanical ringing noise on air cooled motorbikes.
the only way is to build sound proofing around the whole generator.
miggs225 there are so many factors to consider. In car, sound gets absorbed in a long exhaust pipe. The longer the sound travels in an enclosed pipe the more it looses the energy and finaly calms down by the time it passes through the muffler which reduces it further to almost quite. The exhaust pipe is purposely hang on rubbers which also helps to absorb the vibration from the moving gas that comes out with a pounding force. Secondly, most genders are two strokes engine.the interval between the firing in the cylinders is very long. If a genset is made with 6 cylinders, it will produce less sound bkoz the firing will happen at close intervals hence sound will come out smooth like bruuuuuuuuu than braaarrrrrrr Thirdly, the sound doesn't just come from the exhaust pipe alone but also comes out directly from the thin cylinder walls. The only way to contain the sound is to cover with a sound proof box.
@@GabrielMaipose very informative 👍👍
The resonator in an exhaust is tuned to a specific engine speed to reduce volume at that frequency of exhaust pulses. Car exhausts usually have a variable resonator that opens up at high speed (pressure activated) that offers a second tuning for the higher frequency. The small engine is probably running at a lower RPM than the resonator is tuned for. I'd try using a scooter exhaust. I doubt if a motorcycle exhaust would have much effect, either, since they're usually tuned for higher RPM ranges.
You got quite the imagination.
thanks for watching
thanks for watching
That's a good thought but, the engine is connected to the generator at a 1-1 ratio. So the engine is set to run at 3600 rpm (which is around or above the resonate frequency of most mufflers) to provide the 60 HZ electrical output. My theory is that the 3/4" pipe connecting the muffler to the engine is too small, therefore keeping velocity too high. I think had he used the short run before the turn to put a larger diameter pipe (like 1-1/4 or 1-1/2) then reduced back to 3/4, would lower velocity and allow the pressure waves to react against one another. A lot of automobiles have this very thing (a resonator) usually behind or built into the Cat.
Thanks for saving me the effort. I often thought a better muffler would make my generator quieter, now I know not to try it.
Thanks for watching. I thought it would work. We’re going to do more experiments on it. Have a good weekend
Thanks for an honest opinion. My same conclusion. Most people would say it was quieter if it was their video. This experiment tells me to look for another option. Thank you for a great video with honest results.
Thanks for watching and commenting. We do a live hangout every Sunday night 8 pm est. Drop in if you get a minute. Have a good one
Make your own muffler, just larger, use a 55 gallon drum lined with something. Might sound deeper. Most sound probably come from engine not exhaust. Put it in a doghouse or shed with exhaust outside shed.
Thumbs up for trying 👍👍 Respect .
The noise was reduced when you walked between the generator and the camera, problem solved...just stand in front of the generator
Thank you for showing that it didn't make any difference. I always wondered if it would make it quite you showed many many people that it doesn't make a difference if a car muffler is connected.
SNOOP U 2 thanks for watching. Have a good weekend
That's interesting findings. I retrofitted the stock muffler from my Triumph Speed Triple motorcycle to work on a Generac generator with the same engine and it's much quiter than the factory muffler. Perhaps the automotive muffler is too high flow for effective sound deadening on this application.
That is kinda what I was thinking. I’m wanting to try a golf cart muffler when I get a chance. Thanks for watching and commenting. Have a good one

A perimeter of small bales 6 ft high or so, blocks out a lot of noise

Plywood is a better choice not nearly as flammable as hay bales
@@100pyatt put a little re-bond carpet padding or horsehair carpet pad onto the plywood and that should make a very good noise insulator, just keep enough distance between the padding and anything hot. Leave the top open and raise the bottom just enough to get air circulation. You can get clean used carpet pad free from most any carpet shop as its recycled and they probably wouldn't mind if you pulled some from their recycle bin as long as you didn't leave a mess
Would make a great bon fire if spark's must to fly. I guess you could wet down the HAY!
@@dennis8445 Wet hay bales can spontaneously combust from time to time as they dry out.
You have to use dynamite to make it quieter, stick a few sticks under it and light them. Run like hell and then you'll see just how quiet it will get.

Hey pal. Stopped in to support and say hello. I met you in one of the streams I follow for sure.
When I first saw you putting that on I was like "WOW THATS A GREAT IDEA!!!!"... Part of me was a little bummed when it wasnt quieter. Very cool to try it though. Loved watching it. I was excited to see if it worked. hahaha
Thanks for sharing.
NYZ Outdoors thanks for stoping by our farm. I was hopping it would work. Sometimes we fail. But now I know. Thanks for watching 👍🏻
The exhaust is definitely quieter without a doubt. It's the engine itself that makes that noise. The intake also needs to be muffled
@@GerraldFarms You tried... i think it made a difference somewhat..... Next step is sound insulation panels for the sides

boosted kid productions thanks for watching
Can assure you it works very well but learned the hard way about over insulating exhaust because had a huge build up of carbon in the cylinder & started running rough after long hours of operation ended up having to pull head off & clean piston & valves but other than that its the way to go.
Build an intake muffler. Believe or not it works
bobelaviador thanks for watching. We’re going to do more experiments on it. Have a good one
Yes Intakte can also be pretty loud
The vast majority of sound on a conventional generator is from the engine internals and the actual genset on them.
That’s one of the reasons inverter generators are so quiet.
Helped my compressor engine.
Yes, the intake makes noise. Use this muffler for the intake. For exhaust, as soon as you can, increase the pipe to 1.5, then flex pipe to a glass pack muffler mounted with rubber hangers. Or just put a plywood cage around the generator (walls angled in just a bit)
A few things I did was add muffler(with equal results) , added a small set of valve springs inside the factory springs (coil over springs like older V8's had), and took valves from a 1.6L kia rio and crudely cut the length of the stems to be slightly longer than the factory valves. That way the valve train noise was almost eliminated . Aluminum transmits harmonics exceptionally well, which is a big problem when seeking to reduce the overall noise these engines produce. If you look at newer F150 trucks, on the exhaust system they have a exhaust clamp with a bar about 6 inches long with a large weight attached to the end of it. I took notice of this and attached a bracket to the engine, drilled and threaded 2 holes, one in front of the other separated by 2 inches or so. Used a long 'all thread' (1/2 inch) , attached a bunch of large heavy washers to the end, and started up the engine. Slowly turned the rod increasing the distance of the weight from the engine. It began to vibrate violently but kept going till it stopped and the noise was almost eliminated. The harmonic frequency was matched , canceling itself out. This alone ,without adding valves,springs, and muffler is by far the best thing you can do to quite down these things. Give it a shot, its cheap and easy , try a 3/8 all thread, it might work better .
Thanks for watching. We’re going to do more experiments on it soon as I get time. Things are crazy on the farm. The all thread sounds like a good idea. We might try some of your value tricks also. Thanks for the info. Have a good week
What part of the engine did u attach the bracket too? Does the adjustment bar run Parallel to the rotating assembly, or perpendicular to it?
The most important thing is vibration control. Right off the exhaust port I used a Stainless Steel exhaust flex pipe (with SS braid on the outside) to isolate the engine from the solidly mounted exhaust as any weak point between the two will fail quickly, as in the aluminum engines exhaust port/mount breaking apart.
archangel20031 Thanks for watching. Good idea. Have a good one
Wrong type of muffler.
T. T. Thanks for watching.
T.T. - wrong because of what? The muffler he used is a baffled chamber. A flow through muffler uses a different technology that absorbs sounds without baffles. Is that what you’re suggesting?
I saw that explanation on another video but not sure if I understand it completely.
I have a chipper shredder that mostly runs wide open when it’s working and it seems much louder than the previous Craftsman chipper shredders I’ve had.

Thank you very much.
Thanks for watching and commenting. There is still a few things we want to try on it. Have a good weekend
I am always amazed that so many people believe the problem with excessive generator noise is from the discharge of exhaust.
While improving exhaust muffler application will have some minor impact.
The vast amount of noise is being produced by the MECHANICAL ACTION INSIDE THE ENGINE.
The MOVEMENT and ACTIONS of the Valves, springs Rod(s) Crankshaft and Piston(s) DEVELOP the MAJORITY of the NOISES HEARD
The Engine case acts like a “bell” in amplifying and distributing these sounds OUTWARD FROM THE ENGINE AT GREAT VOLUME.
A better approach would be to construct or apply an insulated cover for the WHOLE UNIT with allowances made for operating temperature and exhaust gases.
But just throwing a muffler on it, is not the answer.
Thanks for watching and commenting. I enjoy trying to make things work better for us on our farm.
Go to Home Depot and buy some sound deadning sheet (stryrofoam) and build a barrier around it.
Won't work. It needs air. Build something around it and it will over heat
I think we understand that part Lo-tech.

Long ago a neighbour put open headers on a mud truck. They came out of the bonnet through holes he made. It was painful loud. I told him perhaps cutting down the pipes and putting glass packs on the open headers may help. I could not believe the difference! It was still loud but not painful nor too harsh. The red glass packs looked great with flap valves on the end.

The noise from the Briggs engines comes through the case. I took carpet and stapled it to plywood and placed it on the 4 sides and top and bottom leaving the the top and side that faced away from the house with openings for venting. It was a big improvement.
Ck Iottest thanks for watching. We’re going to do more experiments on it Have a good one
@@GerraldFarms, I've always wondered about this and glad to see someone try it. The other problem with the Briggs is oil consumption. I gave up on my Briggs and went to a Harbor Freight. The electrical wave is "noisy". Electric motors run by it sound different and buzz. The engine itself is much much quieter though and fuel efficient. Bottom line if you want a quiet, long lasting, good signal generator pay the big bucks but that make life less of a challenge and less fun :-)

Which will make a BIG difference

Yes, a car muffler will help HUGELY! I did one on my 5HP B&S 20 gallon air compressor and it helped, but those air cooled engines are still LOUD as hell and putting the whole thing in an enclosure will also help HUGELY. I recently rebuilt a 3 HP 1700 watt generator, a 1979 3W091A Dayton/Onan generator and installed my Air compressor exhaust using a few lengths of black gas pipe for connecting the two and it's not bad at all.
