Loose muffler

The muffler on my 32 is loose after some 20plus years. Has anyone had the same issue with any luck removing the tailpipe and tightening it. My concern is the stud breaking. I don't notice any exhaust leak or noise while traveling-is it possible that when warm it is expanding and sealing?

Hello Steve Dalphonse,

Looking at 'The Filling Station' expanded picture of their exhaust system item: EX-29-32, it shows a stud at the end of the head pipe. Is this the stud that you refer to? I have not worked on the exhaust system on these cars. To guess, I would think that this stud anchors the muffler to the head pipe inside the muffler. If so, and the muffler appears to be loose at this location, maybe your mufflers stud hole mount area is rusted away. Just guessing. An exhaust stud and nut inside the muffler, I believe, may be frozen and a lost cause to try to tighten. A strong light and close inspection of the area is suggested. An alternative may be to look at the front of the loose muffler where the head pipe enters. Could L-brackets be attached to the face of the muffler (spot weld, rivets, self tap screws, JB Weld) that surround the head pipe and held to the pipe with a bolt-on clamp? That may tighten up the muffler. If L-brackets make for an ugly installation, with imagination and metalworking, a custom clamp-shroud might work. This may not be what you are referring to, if so, disregard.

@harry-truppner Yes the stud anchors the muffler and forces it forward to seal on the bevel of the exhaust pipe. I am hoping to find someone that may have had the same issue and have some tips . One thing I may consider is a band clamp at the muffler inlet.

@steve-d It sounds like you have the "slip on" muffler. I don't think you will find anything to clamp at the front. I have several of these mufflers but I have never actually seen the exhaust pipe that works with them. If you twist off the stud, I would think that a local muffler shop could make an effective repair (I'm thinking Stainless steel bolt) so that your muffler or a replacement could be re-attached.

@35mike Yes it is the slip-on muffler. The stud is at the end of the exhaust pipe so you are probably correct it MIGHT be able to be replaced . Looks like a Winter project so if new parts are needed there won't be panic to get them quick.

The 1932 does indeed have a stud on the end of the exhaust pipe and a plate with hole inside the muffler. It is necessary to remove the tail pipe to access the nut on the stud and tighten or loosed it. If the stud is broken in the process of attempting to tighten the muffler can be slipped off and a new stud installed. Would be easier to remove the exhaust pipe to weld on a new stud but a lift and good welder can do it from underneath.

@chip Thanks Chip. I don't have a lift and I agree it would be much easier with one. Just getting under the car and back out at my age (79) is a challenge. If I can find a shop that is willing to do the job that is where it will go.
