Nice job!

I wend down to my local muffler shop that does custom stuff. He had a flange machine and made about 5 of them for $25. I took an old one for him to look at.

Any more where those puppies came from?

I compared it to what's left of mine and except for the length it is same outside. I took the old one apart before. I wanted to see how this one was made so I took this flexible camera to look. The construction is the same but there not a blocking metal piece right behind the inlet. Plus the...

Well guys, NOS stuff is still out there. This Sat I went over to a guy’s place 1 hour from here cause he said he had some M211 stuff. So I get there and he has an old M211 sitting in his back yard, not for sale. So he is older and wants to start selling stuff. So we go in his shop and...

Without shipping and having to pay the local guy to fix the flanges it was $280. I figure that's not to bad for a custom job.

Well it took awhile but I worked with the United Muffler guy and had them build a muffler. I had to go with a standard size that they have so the oval size is bigger than stock. The length is the same. Since there is a lot of room under the truck I don't think it will be a problem. Their...

Brian has all the exhaust parts except for the muffler. I still plan on making one. Right now I have too many other things to do.

That picture was interesting. On your muffler the mounting metal just above the inlet looks totally different from mine.

I just took the center pipe with me to see if the flange he made would fit. So I happened to asked him if he could make the center pipe and he said sure. I am not getting him to make the center pipe. He only charged me $15 per flange. I will spend almost that much buying a pipe to make one...

Well the first step is done. I found a local muffler shop that can create the flange for the pipes. I also showed him an NOS pipe, the one that goes from the manifold down pipe over the drive shaft and to the muffler. He said he could make those too. Next is to create some sort of form to...

My plan is to try to make the 2 1/2 inches inlet and outlet flange pipes first. I bought some pipe at the local auto parts store to try and make the flanges but I want to find a heaver gauge. Years ago I bought some metal shelves from a warehouse that was closing. These kind are the flat...

Well they say Heavy Duty all Welded Aluminized Steel. That price is about double the price of a standard muffler in stores. But then again we are talking custom. I have been giving some thought to making one but mine would not have an Aluminum coating. But you can always do Cold...

I sent the drawing to United Muffler yesterday and got a call back today. I half knew what they would say ahead of time. They do custom mufflers but only in certain sizes. So the guy said the closest size they can custom make that matches the M211 6 1/2x10 is their 7 x 9. So now I need to...

Ok. I know it has taken weeks to complete this. I had to fight the urge to work on the truck and do this diagram. Study this and let me know if I have any of this wrong. Remember I was working from a rusty old muffler that was compete but had holes and no ends. Once we think this is the...

I thought it looked simple as well. I will take some measurements later today. I would choose a heaver gauge metal than the original to make it out of. Alan

The second thing I have done to my M211 is take the crusty but complete muffler off. I think this is a very doable reproduction project. This might be my winter project. Here are some pictures. Alan
