Original Muffler????? Take a look??Opinion Please

[msmaron]

Just found this and did some measurements, Seems all correct including same size tail pipe and intake from end to muffler and out again. Any opinions would help please. To answer some other questions, i am aware that an Aries muffler is great and it can also be used in fine point, however i am asking for reference purposes and originality.
I have included some important pics including welds, and but welds in the muffler body etc.

Thanks in advance

This should sort it out. The Aries is supposed to be made to origianl specs.
I wish I knew who it was so I could give credit to the first guy who posted this picture.

I do not think its original. The originals were held in a large machine and the ends were struck against the center, arc welding the parts together in a butt weld. This one appears to have ends that have been slipped together and lap welded. the attached pic is an original.

Mark, the photos you posted are 100% NOT of an original muffler. Look at the bend under the manifold.

The inlet pipe has been bent with a muffler shop bender, not a mandrel bender like the original. The flange also looks undersized. I vote for reproduction, and not a very good one.

Note: I "flipped" an old photo I took which accounts for the "missing' seam!

For folks that aren't familiar with all the unique characteristics of the Ford muffler, I would suggest focusing on the tailpipe as the most obvious. You will note there are no straight sections and it certainly doesn't have an inverted "V" shape.

As you can see above, although all the radii are too sharp on the Aries it does a fair job of mimicking the Ford muffler assembly.

ok guys thanks for the opinions...for 2.00 i cant complain and it is usable.

[msmaron]

Based on what You are saying Marco..this tail pipe answers the aftermarket question clearly.

[Marco Tahtaras]

I should have added that all the radii are fractional measurements i.e., not even inches. That makes them non-standard and the tooling very expensive. That is why you will find the original shapes ONLY on a ford muffler.

Also the pipes on the originals are the same size throughout, even in the bends. From my understanding this is because of being mandril bent and a steel ball being pushed through the pipe while it is in the mandril to expand the pipe. Modern exhaust benders compress the inside radii and cause the inside curve to be smaller than the straight sections. Notice the bumps at the beginning and end of the bends.

I'm not sure where I learned this (--or whether I dreamed it) but isn't there two versions of the muffler assy, ...or maybe the best way to say it is one revision of the original design?

The earlier header pipe was shaped different but I haven't had time to find the rest of the story. As it stands now it's a puzzle with missing pieces so things don't quite fit. In either case the rest of the muffler is the same.

The above is an article that I wrote for Arvin when I was working for them. I had hair then.
I have an original blue print that we used to build the muffler to. It is old and I had an Arvin draftsman redraw it.
It will appear in MARC when I submit it.

Ron, Thanks for the good information, but I don't understand the last statement. Why would the exhaust of big cars have to be 50 feet long?
