Tractor mufflers

I posted a pic of my 300 in bass's post about painting his 300. Used red mn caught me having no muffler on it. ( It won't fit in my garage door with it on). I always have it on when using it. Question is this. Once upon a time I had a muffler that was given to me by an old gentleman who owned a few Farmall. It was quiet and the tractor had a deeper tone to it. It ended up rotting out. It was replaced by several cheaper mufflers from tractor supply of which are louder and sound tinny. I kinda liked the older quieter one I had for a while. I understand the cheaper ones I bought are pretty much straight through with little to no baffles. Who sells the good ones, and roughly how expensive are they ? I think the one I had that I liked actually had IH stamped on it. It was given to me in the late 90's and it was used when I got it.
 
I have tried straight-thru mufflers on my H [too loud] and then I t tried an internally-baffled one [ ok ], but a little loud at first. I found that as time went by, the soot built up inside, and it got quieter, and now it is hardly noticeable.
 
I have a good (used) OEM on both my 400 and M/400 Frankentractor(Frank). I would trade for a (Loud) Stanley.
 
Stieners have stainless mufflers that are seconds, which means they have blemishes on them. They are a lot cheaper than a good stainless. I have one with the smaller output tube and it is very nice to use. I had one with the large opening, like an M, and the sound from it on any pull would deafen a person!!! This one is very quiet.
 
I believe what you want is the original style muffler that came on the H and 300 tractors. Ken Updike had these re-manufactured several years ago. The are very quite and sound and look just like the muffler your tractor came with from the factory. Steiner Tractor and other antique part suppliers sell them. The Steiner number for a 300 is IHS500. I bought one for my 400 a couple of years ago, IHS1923, for $69.00. It is very quite compared to the OEM muffler I had on it from Case-IH. I was tired of listening to the noisy no-baffle OEM muffler. They also are available in stainless steel but are about twice the price. Al
 
I looked at those "restoration quality" mufflers that Steiners sells and they are NOT internally baffled. Put lenses on both ends, and you'd have a telescope!

The Stanley IH-13 muffler is internally baffled, and is the same inlet size as the IH-4 and IH-10 which are typically used on H's and M's as replacements. It is a taller muffler though.
 
I cannot say what Steiner's sell as a "restoration muffler". But the 400 muffler's I bought from Madson's Service in St.
Nazianz, WI. lists them as the IHS1923 for $69.00. This is the muffler Ken Updike had re-manufactured as the original that
the M and 400 tractors came with from the factory. He also did one for the H and 350. I had been using a Stanley IH-10 and
then a Case-IH OEM replacement on my 400 & 450. But this IHS1923 muffler is far quieter than either the Stanley or the OEM
IH. I have not looked to see if they are actually baffled, but they are quiet. I will look at mine and see if it is baffled.
I can't say anything about a Stanley IH-13 as I never tried that one. Al
 

I have a muffler that came from Case-IH. It is on my 1940 H. It does have the baffle. It IS quieter than the straight through style, but not as quiet as the originals with the smaller diameter pipe.
 
I agree 100%! The OEM I had on my 300 bellowed so loud my ear plugs could not reduce the noise very much. The 2 inch outlet made it even worse!!!
