We have a 1926 Coupe under restoration and need dimensions of the parts for a muffler. I was given enough flat stainless sheet metal and round tube to make one. I think the outer shell is 12" long and 15-5/8" in diameter. Our T went thru hurricane Katrina in 2005 and hurricane Betsy in 1965 so we only have pieces of the exhaust system.
This is dependent on whether or not you have an original tailpipe, as it originally was part of the muffler. Suggest you check past threads, especially in forum 2016 on mufflers--to many questions to for me to answer in one posting (I'm on dial-up, so my responses are limited, sorry!)
If you want it right, you almost have to make up a pipe. I made 50 of them a year ago. Gaslights muffler ends look very good, and the shells are available from the vendors. If you buy a modern reproduction, it will do the job, but are not correct. What I've always done for mine is to find original parts at swap meets.

@John Page Sorry, 15-5/8" circumference, which is 5" diameter.
@Larry Smith, yes, I have to make the entire pipe and already have the stainless.
From another thread, seems like center tube is 3-1/2" which is 11" circumference (I care about this because I have to start with flat steel.) Will take pics of my muffler fragments and the stainless supply. Be prepared to laugh.
Thanks gents for the photos and yes I have seen some. However, what I need are the dimensions of these parts. How deep are the bosses of the center and middle circles on the end caps? What size screw 1/4, 5/16? How wide and long is the oval outlet. No, I do not have a tail pipe after the muffler.
Here's a picture of a batch of authentic replicas of an original tailpipe. The rusty one is an original.
thought this might give you an idea of what they look like. In John's picture, the portion from the muffler to the manifold is a separate piece, as most reproduction pipes are done.
The flange can be measured from what remnant I have left of my original. There are three bends? What are the lengths of the four sections, or what is the distance from the end to each bend?
Here's a picture of my interpretation of the transmission oil screen made from this scrap stainless.
The grab bar happens to be the perfect size for the pack nut.
I'm going by the 12", 13", 14" dimensions I found on another thread.
The outer shell is complete and I don't call that welding. I just drop stainless 308 balls.
The middle shell is a compromise between muffle and back pressure. There are (8) 5/8" holes or 4.9 square inches of escape area for gasses to flow out.
The center pipe will be one piece to the pack nut flange.
My first experiment with an end cap went as expected and I have no shame displaying its glory here.
I'll probably use a 5/16" stainless fender washer on the end w/o spring tension unless I run into one.
