NORS Muffler
Just found and bought a Model A muffler assembly. I suspect it is a NORS Midas unit as it has a thin coating of what looks like gold paint and was found in a Midas shop. It is tapered like the original and has the number H4H301 impressed in the casing. Can anyone confirm that this would be a Midas unit and if it would have a sound comparable to the original? By the way, did you hear about the guy who discovered that he had the Midas touch? Everything he touched turned into a muffler LOL

Re: NORS Muffler
Thanks Gary. I'll measure mine and see how it compares. Are any of the ones in the photo the same measurements as the original? How old is this info. I doubt if any $50 facsimiles are on the market today. Amazing info! Surprising what is out there if you ask.

Re: NORS Muffler
The midas mufffler sounds nothing like the original. It is louder, as it does not have the baffleing like the original. They also produce more back pressure than the originals and therefor produce more heat in the floor and the engine.
I use Aries mufflers, and will not use a midas. |

Re: NORS Muffler
What's your opinion on the "round type"? I have one of those that I bought years ago from an auto parts store.

Re: NORS Muffler
The Midas or "$50 facsimile" type mufflers are still floating around out there. I bought a new and unused one from a fellow last year at a swap meet. He had 6-7 of them and soon after I left another guy bought the whole remaining lot of them.
Does anybody know how these could be modified to lessen the back pressure? |

Re: NORS Muffler
I have an Aries on one of my 5 A's. It makes the world of difference. Although that car has a great motor as well, the sweet music from the tailpipe is beautiful. As I wear out the exhaust systems on the other cars, they will get replaced with an Aries. Jeff

I expect the construction of different brands of muffler will vary but with the one I had, I cut the tail pipe almost off and bent it aside. (Almost off so I didn't loose alignment) I then made a hole (5/8") in the baffle half way along the inner pipe and welded the tail pipe back in place. The result was still that Model A chortle we all know but with a little more "authority". To avoid pushing the baffle out completely, I made a pilot hole with a .22 rifle! Then I drove a piece of 5/8" rod sharpened to a square point though the hole after shaking the bullet out through the engine pipe.

Re: NORS Muffler
I doubt that I've ever heard the sound of an original Ford muffler and doubt that many are still around . Over the years most of the mufflers that I've had came from JC Whitney . Being as I've never heard an original muffler I can't really compare the sounds . All of the replacement mufflers that I've seen in the past nearly sixty years have been bare metal . None have been painted gold and I've got to wonder if Midas made any of them . The less expensive mufflers are still around but most model A vendors no longer handle them . A guy that I know told me that he bought one from some model A vendor for $150 dollars but I don't remember the name of the place . I bought several of the low cost mufflers for around thirty dollars each from an exhaust pipe salesman a few years ago . I can gut and use these mufflers in my cars . I should have over a lifetime supply , depending on how many more model A's that I build . I've had the low cost mufflers to last forty years. My daughter was bad about backing over stumps or they would have lasted longer . They all look pretty much the same . I figure that most if not all of the low cost mufflers in the past 55 years have been made by the same place. There have been at least a couple of stainles steel mufflers like the Beaver and Aries mufflers but they were expensive . JC whitney offered a round glass pack muffler in the sixties . I figure that most of the tapered mufflers used on model A's were the low priced mufflers . I remember when JC Whitney sold them for around $7.95 each . Before that I just ran straight pipes if I ran anything at all .

Reading this straight after Purdy’s detailed post was a crack up!! But thanks to you both for sharing your methods in useful detail. I guess it verifies that there’s more than one way to skin a cat! |

Re: NORS Muffler
Lots of interesting info. Thanks to everyone who contributed. I appears that what I have is a $50.00 Facsimile Midas muffler. Coincidentally, that's just what I paid for it. I think I got my moneys worth as I could use it as is or modify it as suggested. For now. I'll leave the round type muffler on the car. It appears from the chart that it will perform very like an Aries.

Re: NORS Muffler
Scuffing an old crummy exhaust system with 80 Grit Emery Cloth & Spraying it with "CAST-BLAST" makes it look like NEW!!
Sumbody mentioned the ROUND Mufflers---Looks like something that should be HIDDEN, under a DIVCO Milk Truck!!! Bill Picky

Re: NORS Muffler
Back in the 90s I had some pipes bent to match the shape of the model A exhaust pipes . I bought a twenty dollar straight through glass pack muffler and welded the pipes to it . I installed this setup on Gus , my rusty june 29 tudor . The glass pack didn't have the model A sound, but was much quiter. The straight through design of the glass pack muffler greatly reduced back pressure and gave a slight power boost over the unmodified fifty dollar tapered design muffler . If original appearance isn't a big concern , this is another possibility .

Re: NORS Muffler
If having pipes bent to shape is too expensive, The pipes off the old muffler can be sawed off and welded or clamped to a glass pack muffler . just another thought .
