I got a stainless exhaust pipe and muffler set a few years back. Although I would/Will likely appreciate their longevity, I'm never been happy with the volume of the muffler.
Is that much consensus on what folks might consider the 'quietest efficient muffler, that doesn't create too much back pressure?
Mine is a '22 rebuilt engine, I believe, but no 'hop ups'.
Just my opinion:
Model Ts with the earlier stock muffler that includes a tailpipe sound quieter to me than Model Ts with the later, snub end stock muffler (no tailpipe).
I run a Thrush high flow 2" ID, 14" long muffler. I use a stock pipe. Nice mellow sound, not loud.
If the inner passages are the correct size then it will make a Model T sound. This is not a RR, it's a Model T and some noise is part of the joy of ownership. That being said, I am now running a tractor muffler and it has a long tail pipe. I do not know what the number is or where is was gotten in the first place. It was on a car a friend bought and he gave it to me. My old muffler was just getting too burnt out. It sounded fine but was blowing out all the joints and I was more worried about blowing sparks out and starting a fire.
I run stock mufflers on all my T's early and late. They are all quiet.
I use FO-11 Ford tractor mufflers on my T's and have for many years. They're straight-through, but not loud. Straight-thru = no back pressure. They are 1-1/2" inlet and outlet, same as a stock T muffler. They're available at farm stores, by special order.
Yeah...i'm not expecting anything super quiet... but the t's at Greenfield Village (albeit a whole lot better mechanics there!)... seem quiet a bit quieter. You can have a conversation with the driver.... let alone a passenger next to you.
I enjoy the best of both worlds. A stock T muffler and a genuine, original, factory (someone's factory anyway), unauthorized exhaust cut-out on my T's. There's times I feel like being loud and other times more like a church mouse.
I have stock style mufflers on my Ts and they are not loud but seem louder than my A models with stock exhuast.
By stock.... do you call mean stock for you car.... or engine, at least? There are several typsmes... all metal and welded... wrapped metal with cast... or pressed metal ends, 'asbestos ' wrap, etc...
Google "mtfca; muffler" I am sure you will get all types of different types that can be used. Close to stock would be the tractor type with a tailpipe there will be strings in the past that will give numbers and places to buy.
While ends construction type material may differ, a tail pipe may be present or not, or they are wrapped they all have about the same size holes inside. The modern tractor type might give you the quiet you are looking for and maintain a somewhat stock look.
Dennis, before you spend money on a replacement, take the end off your existing one and check that the inner baffle is in the right way around. Its hole should be towards the front of the car. If it has the hole to the rear, the exhaust gasses have a much shorter path through the muffler, and the noise will be louder.
Hope this helps.

I took the 2 inner baffles OUT of the repro muffler on the 18 (cast iron ends-original?) so I could hear it and it's almost loud enough but I'm used to the 24 with a 2-1/4" drive shaft for an exhaust pipe. I can hear them both now. Well, the 18? Just. If I turn my head just right... :-) I left the outer tube in place. He's pretty quiet.
These little buggers are very quiet with a proper muffler and yet I remember another fellow remarking how his T, with what I guessed a correct muffler was "too loud".
I'm a stickler for running the correct mix on any gas engine so that taints my opinion. :-)
And I'm deaf as a stump. :-)
Dennis, my repro regular steel stuff is 30 years old/brand new.
Wait a minute (I sound like David Byrne), Mark O's T seems to be plenty loud.
What am "I" missing?
While I have been typing, Allan may have the answer.
Yet, I have 2 inner baffles laying in the parts bin. ???
Stock is stock period! You can do what you wish. As I mentioned, I have 100% stock Ford mufflers on all of my cars, and they are quiet. Of course the 1920-27 mufflers use a special exhaust pipe, and they are difficult to find.
Stoc is stock... kinda. As i mentioned above, Henry came up with several iterations of a stock muffler. My question was which one is quietest.... also knowing, that's proba ly more of a personal opinion for most.
My beast is far from a museum piece, but I am trying to keep a decent incarnation of a '24-ish.
"Stock is stock period! You can do what you wish."
All this "original" talk wears thin when coming from someone who has a Scat crank and high-compression head on his T.
.....also,.....not to mention aluminum pistons, right?
I wish I had a high compression head on my '25! I would like to find a Ricardo head to make it go faster. Other than that, my '25 is the sweetest running T I know of, with a stock crank too. I do admit to having aluminum pistons and modern valves.
What about your '13, Larry?
Now back to the subject at the top!
I run a FO 11 from rural king and an angled tail pipe from pep boys with universal hanger and clamps. Keeps fumes out of the passenger compartment.
I just ordered a stock muffler from Snyder's to replace the generic one that came on my car. Looking forward to it sounding like a "T" and not a Toyota.
Which flavor did you get? Cast ends, pressed, etc??
Maybe take a before and after video??
Hmmm... come to think of it... I have a trouble meter app on my phone........
Many may not be aware of this, but the 1920-27 exhaust pipes are actually part of the muffler. I made a run of 50 of these pipes about a year ago, and the sold right away. It was a lot of work, and even though the way I had the bead done wasn't the way Ford did it, the people who bought them seem to be happy, I hope. I only wish that someone with lots of $$$$ could do it right.
Dave Dunn ... how did your muffler Chang go? Which flavor T do you have now... a Ford T or a Toyota?
I'm mostly considering standard steel end muffler vs cast end... noise wise. I might indeed just go with a tractor type, though, if actually quieter... at least for daily driving.
The stock Model A muffler seems to have a nice "ring" sound to it that I find to be a very pleasant sound. The Model T never seems to have this distinctive "ring" that the Model A has. I wonder if anyone has ever adapted a Model A muffler to a Model T, and, if so, I wonder if it then produces the same pleasant "ring" sound to the Model T exhaust that is always present on the Model A,...??? Anyone ever tried it???
Dennis, the muffler change was a piece of cake, 15 minutes start to finish. My T now sounds like a T should. I used the steel case muffler from Snyder's. It's quiet, the car is a pleasure to drive with no exhaust leaks.
Good news! Thanks!
Larry, even though those exhaust pipes weren't "exactly" the way ford made them, they are way better than any others out there. As far as I'm concerned, they are made as "right" as they need to be. I hope you will make another run of them in the future, or at least give someone else a chance to. I think the way that you made the "bulge"(for lack of a better name), was a stroke of genius. JMHO Dave
This is for Harold. My friend Bob has a 27 Tudor with A crank, A cam and A exhaust manifold. He uses a Model A muffler and IMHO it sounds more like a Model A than a Model A, if that is possible. Very chirpy!
Well,.....thanks for that Tom! Always wondered how the exhaust of a Model T would sound with an "A" muffler. Of course, the "A" crank, cam and manifold might add something too, but I would suspect that it's mostly the "A" muffler. Thanks again Tom,.....harold
Well, worked on my muffler setup a bit more diligently last weekend.... in the process, took the muffler right out and 're-negotiated' the mounting flange, as well as the input pipe. The inlet and end of drop pipe never did fit very well, so cut slits on the inlet pipe, and flared it out a bit (didn't have a good fitting swedge). The inlet finally sits enough over the drop pipe so the muffler clamp can get a goodngrip, and seals properly. While out, I stuck a flashlight in the tailpipe end and saw that the muffler is basically a through-pipe, with little appendages sticking into the airway, as baffles. So, not suprise g that it sounds the way it does. With the inlet setting properly on the drop pie, and the mounting flange adjusted to accommodate, at least most of the sound is going out the tailpipe.... and not the drop pipe , now.
I'll likely order a stock muffler next spring and see how it sounds.
We had a member in our chapter that had a local muffler shop fix him up. They installed a Dodge Neon muffler with a tail pipe. It is very quiet and keeps the soot off the axle and such.
Interesting topic. When I am driving in my neighborhood here in Rochester I can't wait to shift to high so that I can cruise with the least sound of the engine. Most of my neighbors like the T, but every once and awhile there is a detractor walking their dog at a place where I'm at high revs in low gear to get enough head way to shift. The '23 is breaking in nicely and I've been tweaking the carburetor and feeling the spark adjustments so that now I can drive at very low speeds with a smooth and quiet engine. Climbing a hill while slowly gaining speed is always going to be a little loud.
