Muffler/exhaust fixation to chassis

The Aries muffler has the correct flange and seals good. A repro manifold and Aries muffler will make your A sound like it should leak free
 
Back to the original question. I believe the clamp is bolted on top of the bottom flange of the chassis. Anybody else? Confirm or otherwise??
That said, I stop the rattles from that bracket by wrapping a single layer of masking tape around the pipe where it goes through the clamp. If needs be, I put a spacer over the bolt to prevent it being done up too tight, yet tight enough to stay put. I then fill the gap between the clamp and the pipe with silicone. You don't have to drive far for the masking tape to burn off or at least get hot enough to lose its stickiness. The silicone will withstand more heat than the exhaust will get back there so you end up with the pipe free to slide in a silicone sleeve which won't rattle. If you wipe away excess silicone, no body will ever see, not that anybody other than a judge will get under to look.:D
 
I have a stock, albeit repro, setup on our Tudor. It is leak free, but I cannot get the BUZZ out of the rear clamp. I am contemplating a silent block at the frame connection with the clamp tight around the pipe.

I either got an oversized clamp or reworked it a little large, and then lined it with welding cloth. It's quiet and still allows the tailpipe to move the 1/2" as it heats and cools.

I agree and confirm that's the way I attached mine

That was my initial question, and also how mine was attached. I'm making it now with a silent bloc like others did or suggested in this thread.
 
In reference to post 25, You are right goodoldvic, Bracket on top of the lower flange of the frame channel. About 1/3 of the pipe dia. lies below, The 2/3 of the pipe is above the flange with the original bracket. I believe that the support bracket fits somewhat snug to the pipe and is a little loose where the bolt goes through the frame for the expansion. The bolt and castle nut with cotter is adjusted to provide movement. There is a good drawing in the service bulletins index muffler p.327.

Ford issued at least one updated clamp for the rear muffler hanger.

There at least two positions that Ford recommended for the location of the holes in the frame to mount the original clamps or revised clamps and a diagram that shows where to drill the new hole for the revised clamp.

So if clamp does not fit you might have the hole in the wrong place depending upon which style clamp that you have!

I don't have the S Bulletins handy to look up the page or pages.
 
I am using the same idea as AL in NY (post #15). Mine looks a little different, but it's the same idea.
 
But thats not factory looking and takes away from the shake rattle and roll thats supposed to be present. I bet Henry is PISSED....
 
I haven't had a whole lot of people looking under there to see how I supported the KZHAUST pipe.

Most are still in shock over seeing my alternator. (among other things)
 
If someone wants to crawl under my Model A and tell me that's not what "Henry" did, well then they can "Knock themselves out".
As for me, I enjoy the quieter ride".
 
Here is my fix. Hardware came from o'Reily's Auto Parts and I modified it.
