MG TD TF 1500 - What car is this muffler for?

I posted this on the TC.A.B forum, but thought I would also ask this group.

Going through my spares, I thought I had an original TD muffler. In looking at it, it's not a TD muffler.

I though TC, but there is no bracket and no signs there ever was one.

Thoughts?

Bruce, This may not help much, but at least you will know that someone else has seen this type muffler.
History, I have had MG TDs since I was 16 years old, so I've seen a few over the years. I began collecting spares, to complete my cars years ago, and I bought mufflers and pipes when I found them at swap meets etc. The muffler you have is in fact a very early MG TD muffler that had the small tail pipe. I currently have two of them myself. What I know?
The muffler with the flanged inlet pipe connection was for the TD and Moss sold them in the early years. Their early catalog showed the flanged muffler available for the MG TD. However, it wasn't too long before they no longer listed this muffler but sold a common MG TF type muffler with bigger pipe as the TD set up. I don't know the year this occurred.
I never found a TD header pipe at a swap meet for this muffler but made one by welding a flange to suit for one of my cars. By the way, the muffler I have like yours has the small tail pipe full length already welded in place.

It certainly looks like an original TD muffler. I need to come over and take pictures of it. Don't throw it away. :-)

Ok, that is interesting. So the TD came with the double flanged pipe from the exhaust manifold to the muffler like the TC.

Another of those items we need to clarify how long they came that way.

I know the bigger exhaust is better for the engine, but if it is original, I may build a pipe and put it back on the restored car. I am shooting for factory correct (as much as I can or we know about)

Chris. Not a heck of a lot of progress on the restoration. Got the frame all painted, chased all the threads and will be starting the rebuild in the next few days. Stop by. I will hold off cleaning and repainting the muffler until you get pictures.

I also have another project relating to fasteners that I want to discuss with you.

Came across an email for Anders Clausager. Going to see if he might have more information on some of the items that we have been coming up with. This being one of them.

The attached scan is from my June 1958 AKD834 TD parts list, with the front pipe part number given as 136190 - and there are no part number changes.
I tried to upload the full page, but it was too large.

I saw this same muffler on an early all original TD at the NEMGTR GOF 102 in Lebanon, NH last weekend. We were looking at this muffler, at first we thought it was a TC muffler, but no evidence of the holding brackets that were welded to the TC muffler and bolted to the frame. We concluded it was not an original muffler, but now I am not so sure that muffler was identical to this one. Interestingly, it was brazed in, no clamps.
Be well,

My father said the original muffler lasted less than a year. And the smaller tailpipe did increase the back pressure so it was usually replaced rapidly.

For those that want the same hangers but a larger tailpipe, the MGA used the same type, just bigger. I am running that on my car.

" When did it change"

I have a 52, Shipped first week in 52. I purchased it in October of 1966, in Massachusetts, in rough shape.
I drove it that winter in Mass, moved to FL in the spring and drove it there until 1969 when I took it apart. It remained in pieces until 2 years ago.

Looking at the pictures, it looks like I have one of the mufflers you are talking about?

I just crawled under and took this picture?

Yes?

Thats it Jim. Same wrinkled look in the folded seam.

Your picture will be very helpful. It gives me a good picture of the bend I need to do on my down pipe.

So it was standard at least until 1952.

I believe I have some parts catalogs from the 1970's. Will check to see what they had.

I have a moss catalog from 1968. Not in that.
If you need more/other pictures let me know.

As far as I know, all TDs and TFs were not delivered with a separate muffles as Bruce has shown. Certainly all TDs and TFs came with a one-piece welded assembly from the manifold to the tailpipe. Look at the TD parts diagram that R Wilson has submitted, and you will see part nbr 114 that is labelled 'assembly'. A check of other parts catalogues confirms this. Hence no separate muffler.

I can recall out local dealer with dozens of the assemblies standing upright in the corner of the stock room, and I still have the last system I removed from my TF last year, and it is still a single, welded piece from manifold to tailpipe.

So that muffler can't be from a TD or a TF.

After the discussion, I did look in my shop manual, which is dated 1954. It shows a flange on the muffler.

The muffler I have does not show signs that the exhaust pipe was cut off, but it could be that the muffler and exhaust pipe were one piece.
