Saw exhaust tones

[P.M.P.]

He can take your hearing to a whole new level with that technique.

I really like that 346 jay.

It's sitting on my shelf. It's a good running saw. I need to fix a better muffler mod up for it.

I took the dual port off my 660 you did...that stock opening is plenty...that NOPE was LOUD.

I cant really tell , but im not much of a cut timer either so my opinion is usless there.

I wanna get another dual port cover that isnt opened up and try that...that one that was on there was too much for me...especially with that wide weave screen.

To my ear a 550 even with stock muffler. Drives me crazy if I don't have ear plugs in.
I'm sure it has something to do with everyone's individuals ears. And the frequency of that saw.

I left my 545 550 mufflers stock after running a 550 muffler modded. Loudest dang SOB stock for small saw. No way in hell I wanted that loud cutting.

Friend wanted me to muffler mod his 272. I said are you sure as we were busting back a few. He was all smiles hell ya.

I said here take this saw muffler modded and then this saw of same series stock muffler. Cut with them both in long cut.

I then ask now which one you want to cut firewood with all day. Lets just say the 272 still has stock muffler on it.

OEM screen will help a lot.

My milling 660 has a can like that ,the stock 10mm exhaust hole ,and a stock solid front cover ,it mills fine still ,lost a little grunt in a 24 inch wide pass but it still chugs along fine ,i will take the power loss over the loud exhaust i had before .

So it could be the porting mods making it louder ? Not the design of the saw ? My other saws are ported also ,but do not hurt the ears .

The exhaust is raised, you get more of the combustion note in the sound of the saw which is a higher pitch that really hurts your ears. I can tell if a saw has more exhaust timing than stock, just like my dad could tell if a dirtbike had a factory pipe or a works pipe.

The 461 definitely has a more irritating exhaust note, whereas the 661 isn't too bad stock but they get irritating after opening up the muffler and porting the jug.

Actually, I don't think so. DBs are DBs, and over time, exposure to DBs above a certain level WILL cause hearing loss. It is cumulative in nature and NOBODY is immune to it. If your ears are ringing after shutting the saw down, and even continues hours later, you are damaging your hearing. Even stock saws and their advertised DB ratings are over the threshold where OSHA requires the use of hearing protection. There is even a point where OSHA requires double hearing protection, plugs and muffs.

It's like shooting firearms. If you do it with no hearing protection, you ARE damaging your hearing. When I was younger I did alot of shooting without hearing protection and now I have tinnitus. It sucks.

Who cares about why one saw might sound more shrill than another. They all will do their measure of damage on unprotected ears.

Use hearing protection. It's that simple.

Not trying to be "Joe Safety" here. Just pointing out that hearing protection is just as much part of your sawing gear as your chaps, hard hat, eye protection, boots, and gloves.

 

[RIDE-RED 350r]

That was Phil!

Believe it or not, Lee's kart saw is louder than Brets ESR 350

The ATC in my avatar pic has an ESR 350 top end... I'm not running an open stinger like that saw, but even with my brain bucket on, it is loud. In fact, after my last ride I'm thinking I should wear earplugs inside my helmet. Ears rang all night after riding for a day on it.

I get what your saying about DBs loud is loud.
I have hearing loss in the higher Frequencies. And for what's it's worth the sound of certain things drive me crazy. It doesn't have to be loud to do it to me.
I've been wearing earplugs every day for the last 20 yrs at work. And I can't stand to be around anything without them.

That 101B is something you need experience in real life. Video does nothing for it.
I'm tellin ya.....it's loud.
I grew up at a moto X track, I've heard some loud bikes, 2 stroke & 4 stroke. None of em hold a candle to Lee's kart saw @ WOT.
And a 450F is a pretty loud bike with a PowerCore pipe

 

[angelo c]

I can't believe you guys run saws with out hearing protection. I vacuum the carpets in my house with muffs on.



Man I must be the oddball. I like my 372s sound. Never thought them to be oppressive.

I totally agree with this statement...that kart saw is effing loud

.......says the guy with an ESR 350 bike saw!

Sup buddy?

 

[TJ the Chainsaw Mechanic]

I never noticed....I have two dual ported 460s and they still seem quiet. I prefer listening to an 044 at wot though. Sounds better. Did someone say loud? Not ear piercing, but will give you a good head ache.
