I noticed that the exhaust pipe doesn't fit very tightly in to the muffler. Thereby flooding the interior of my Tudor with fumes. What do people do to fix this problem? wrap the pipe with some kind of material to fill the void, or cut a slice in the muffler pipe, or both? Thanks.

By the way, the pipe does not have the correct bend to line up with the muffler..... Ugh

John I believe the pipe is intended as a slip fit without a clamp in order to allow it to move as the frame flexes. It is possible that your exhaust pipe is too loose because it is the wrong diameter or that your getting too much back pressure from the muffler because it is clogged.

My exhaust pipe fits the muffler perfectly. It is a tight slip fit and I do use a clamp. One thing that I learned years ago was to (if possible) get all of the exhaust parts from the same manufacturer.

Had that on one of my cars..can't remember which. But I "globbed" it up with furnace cement and that stopped it. Chassis flex never bothered it.

Had the same problem on my coupe, so wrapped the joint with a piece of heat exhaust ribbon held on with 2 hose clamps, extended the tail pipe several inches and ran a sealer around the trunk floor. All's good now,

Thanks all who made suggestions. I forgot to mention that the tail pipe and muffler are brand new. Guess I'll have to somehow bend the pipe so it all fits.

The exhaust pipe should be snug but not be clamped to the muffler at that point. One thing I might suggest would be to get a good tin can and cut a piece which you can wrap around the exhaust pipe and slip it between the muffler pipe and the tail pipe. Then put a clamp around the can and the exhaust pipe, but let the end in the muffler un- clamped. That way the fit will be a bit more snug but still be able to move inside the end of the muffler. Sometimes the bend on the pipe between the manifold and muffler does not fit because the frame sags on the right side. This is caused by torque on engine and also by torque caused by the transmission brake. Both tend to lean the engine toward the right and eventually it will sag on that side. And the the steering will even pull to one side. It might even take some shimming on that side of the body to get the doors and hood to fit correctly. Shims and different bend on exhaust pipe are temporary fixes, but best corrected by straightening the frame.

Some reproduction exhaust pipes and mufflers fit better than others. I use a muffler clamp to hold the pipe to the muffler, I also brazed the ends of the muffler to the muffler sides to keep it all together for the occasional backfire. No, Ford did not use a muffler clamp or braze the ends, but the new reproductions are not made like the original Ford parts.

The muffler with the cast iron ends was mounted at both ends, so the tail pipe was a slip fit. When Ford went to the pressed steel ends, the muffler was only mounted at one end with a steel strap/hanger. With that original setup, the tail pipe went all the way through the muffler, making it a one-piece unit. When installing the modern pressed steel ended setup, it would be clamped at the front, so it ends up being like the original setup. The steel strap/hanger is what allows flex from expansion and contraction. I don't recall running into that big of an issue using the reproduction pipe, even if the bends are a little wrong, except having to trim it to fit, when using the pressed steel ends.
