Straight pipe exhaust

I?m thinking about putting a 4 foot tall stainless
Steel exhaust pipe on a farmall 560 gasser .
For everyday use . Most mufflers are a straight
through design anyways . So noise level shouldn?t be much
louder ?
What do you all think ?
Thanks
 
I seems like a good idea, but a better is to have a real glasspack installed in a chrome pipe. Your hearing is threatened. Oh yeah, I can't here you. Jim
 
I agree, mufflers with a baffle are out there. After 6 hours of work you will realize that there is plenty of bark.
I bought a 966 with the chrome pipe, after 15 minutes I went back to get ear muffs.
 
Cheap way to do what you are wanting to do and not wreck your hearing.

I welded a piece of flat plate on top of the pipe that screws into the manifold on your 560 and then bored holes to accept a Deere A or 60 muffler.

A 4" chrome pipe fits over the Deere muffler perfectly.

I did this to a 560 back in the mid 70's, I did have to change the Deere muffler and get a new straight pipe a few years ago, but it worked fine.

If you don't want to tell anyone your IH has a Deere part on it no one will know because it's hidden! (-:
 
I would vote for a muffler. Got a stainless straight pipe on my 300, only comes out to parade. I don't think it would be an enjoyable experience to run it like that all day.
 
I have been around equipment a little too much, now at 59, I just say what.

Protect your hearing while you still have it.

Loud is not cool, it is foolish.
 
It's one thing puttering around the yard, it's another thing to have the plows down and working the tractor.

True, straight thru mufflers are not as good as one where the gasses have to change direction, but they are far quieter than a straight pipe.

You only get one set of ears.
 
There is a online site (ROD Shop) that makes 2FT. stainless steel 45 and 90 degree pipes with a muffler inside. They can be had in loud to quiet muffler inside it.
 
We had a Farmall M with a straight exhaust and no muffler. My Grandfather didn't care because he was deaf anyway. Without good hearing protection it was horribly loud. It now has a muffler.

(quoted from post at 00:47:43 01/15/19) My hearing aids cost $2,600! Don't do it!
That is a good price. Many people pay twice that much.
For those of us using hearing aids, check out Costco for good prices. Service varies by location but you can get the free maintenance & supplies at any Costco. You still need to buy batteries but theirs are not bad at about 33 cents each for size 312.
 
Yes, I have two polished stainless straight pipes on both my Farmall's, Stage 2 Super H and a '51 M Dad bought brand new. But the normal use of both tractors is idling around doing loader work. If I had something serious to do that actually put a load on the engine I kept the two Stanley mufflers that were on them when I got them, which I HATE the sound of. When I get a spare $400 burning a hole in my pocket I'll buy a polished stainless steel Muffler Bermuda KEN pushed into production. I'll get the 460 muffler for SH, and M muffler for M.

If your 560 spends any time really working keep a muffler on it. And a 4 ft pipe is WAY too long. 3 ft is longest I'd go.
 

I made a 3" diameter straight pipe for my 1940 M. I LOVE the sound of it, but listening to it for about 4 hours while pulling a plow was a little too much. I put the muffler back on. Straight pipe is stored away on a shelf.
 
Good hearing aids cost more than a good 560. Do your family and your neighbors a big favor and go with a muffler, they won't want to listen to a straight pipe even if you do.
 
I have a 3 1/2" on my 450 that I tractor pull with. When it gets under load it barks so bad you can't stand
it. I have went back to a baffled muffler and it pulls as good with a muffler as it did with out and your ears are not ringing.

I have a Stanley, made for the tractor, on my MH44 EFI, it is still way too loud that way. I am going to adapt an automotive muffler this winter. I think it is the compression ratio that makes it so loud, at 9:1.
 
for chores or yard work its ok not that loud . but get her in the field under load and she will be barking. plus 4 ft way too high. I think the muffler is like 28 inches.
 
Get a muffler. Without one, each time you use the tractor you will lose a little of your hearing. The loss from each exposure won't be enough to be noticeable but each loss is permanent and accumulative. You have had and will continue to have unavoidable, one-time exposures to damaging levels of sound; their accumulative damage will stay with you. Add to this the normal loss of some hearing with age. You can't allow exposure to damaging levels of sound - that could be avoided - to add to unavoidable and age related losses. Get a muffler.
 
sure funny no one has said a thing about exposure limit on this loud engine. a person is allowed 85 decibels for 8 hrs. no one has even mentioned about ear protection like wearing ear plugs. I been around noisy engines on drilling rigs for lots of years, where the noise is way higher than an old tractor with no muffler.
 
Muffs and plugs are effective - but only if they are used. If they get misplaced, people have the tendency to go ahead with the job rather than lose time looking for them. Noise exposure that causes total deafness is rare. Don't confuse total deafness with partial hearing loss. Partial hearing loss usually occurs over a period of years, too gradual to be noticed. A hearing test would show you how much of your hearing is gone.
 
I had a 4' straight pipe on the 300 for exactly one week and took it off. It was great idling around the yard and just sitting around, but the minute it was under a load it barked so loud it hurt your ears! I bought a muffler the next day, lopped the pipe off and set that sucker on there. Been like that for a few years now and my hearing is better for it.
